Let a is the first term and d is the common difference .


(m - n) = -2a(m-n)/2 -(m-n)(m+n)/2+(m-n)d/2
1 = -2a/2 - (m+n)/2 + d/2
1 = -1/2 {2a + (m+n-1)d} ---------(1)


from equation (1)
S_{m+n} = -(m+n)

Gerrard was a playwright. He lived alone in a cottage. He was an intelligent person with a good sense of humour. He knew how to handle an adverse situation. He had a lot of patience too. one day an intruder entered his Cottage. when gerrad came to know about his intention. He was not scared at all. He had Presence of Mind. He was very good at story making. H immediately convinced the intruder that Gerrard himself was a criminal and police was after him. The Intruder got convinced by him. Gerrard managed to get rid of the intruder by locking him into the cupboard one Learns from him that one should never lost one's wit in adversity. His Presence of Mind,wit and sense of humour saved him.

Can you don't tell according to n.c.e.r.t lines which can be easier for understanding

ANSWER=................. Prediction of Period ⟶ In the electronic configuration of an atom, the principal quantum number (n) of the valence electrons represents the period of an element..... .. .. . ... ... ... Prediction of Block ⟶ The orbital out of s,p,d and f which receives the last electron represents the block of an element.............................. ....................... Prediction of Group ⟶ The group prediction occurs with the help of block as:- ............................................... (1) For s block: Group Number = Number of valence e− ......................... (2) For d block: Group Number = Number of e− in (n−1)d subshell + number ............................ of e− in ns subshell ..... ... . (3) For p block: Group Number = Number of valence e−+10 ...... B..... (4) For f-block: Group Number = 3 (always) ........ For example for chlorine with Z=17 ....... ... Electronic configuration = 1s22s22p63s23p5 .. .... Since the last e− enters in p - subshell: ...... ... (i) ∴ Block will be ′p′ . ...... (ii) For group we have element in p-block ... .. ∴ Group number = 10+ Valence e− in s subshell + Valence e− in p subshell . ... . . . Group Number = 10+2+5=17 . . (iii) For period . . The quantum number of valence e−=3 .. . ∴ Period number = 3

Character is feature of the organism or external appearance of the organism.Trait is inherited character and it's detectable variante.g consider one character as Height of plant, it is external appearance or feature while, tall and dwarf are there trait .Traits are in multiple forms and environmentally determined.
Character is a heritable expressed attribute of an organism. Whereas, a trait is a heritable variant of a character. An example would be a phenotypical expression of eye colour would be a trait of the character coloured iris in the eye.
both are same superficially but in terms of genetics both are different. In you read genetics book then you read all time traits are transmitted from one generation to another generation or in simple words from parent to progeny traits are transmitted. You never heared like characters transmit from one generation to another generation, but you heard about phenotype or character of progeny is tall, small, red, yellow, round etc. So in simple words you can say trait is transmitting factor from one generation to another generation and character is a visible factor.c

In Maths or Geometry, a circle is a special kind of ellipse in which the eccentricity is zero and the two foci are coincident. A circle is also termed as the locus of the points drawn at an equidistant from the centre. The distance from the centre of the circle to the outer line is its radius. Diameter is the line which divides the circle into two equal parts and is also equal to twice of the radius.

Morphology:- Study of external features of an organism.

Morphology is the study of physical features of an organism.

Morphology is the branch of biological science that deals with the study of form, size, colour, structure and relative position of various parts of organisms.

Importance of morphology-

1. Knowledge of morphology is essential for recognition or identification of plants.
2. It gives information about the range of variations found in species.
3. Deficiency and toxicity symptoms are morphological changes that occur in response to shortage or excess of minerals.

In the series successive terms are formed by skipping the two alphabets in first letter nd three alphabets in secondletter 
AH after A two alphabets are skipped and after H three letters are skipped. Hence next term is DL.
Similarly continuing the series the next letter will be MX 

Starting with the first number ‘1’, we move ahead in the way given below:

1 x 2 + 1 = 3

3 x 2 + 1 = 7

7 x 2 + 1 = 15

15 x 2 + 1 = 31

31 x 2 + 1 = 63

63 x 2 + 1 = 127

Therefore 127 is the next number in the series.

Maria sharpova is a women of firm detrmination. She has a strong will power.She is mentally tough.At the age of 10 when she was sent to USA for training, she faced many problems but she never thought of quitting.Difficulties made her more tough. It is due to this toughness that she bagged the ladies single crown at Wimbeldon in 2004.In August she became the world's number one women in woman's tennis.

                                Maria has self confidence.  She realized at an early age that in this competitive word she will have to work hard to achieve the top most position.So she works hard.She is patroitic to the core.She is proud of her russian  roots though she loves USA. She says that she has russian blood in her veins and if russia wanted her to plat in olympics she will do this

According to Keats, suffering and pain caused by man’s malice and his evil ways spreads the pall of despondence over our dark spirits. Man lacks noble qualities and his hostile and inhuman nature makes the world gloomy. This can be removed by some shape of beauty that is a source of constant joy.

The radius of 1^st circle, r₁ = 21/2 cm (as diameter D is given as 21 cm)

So, area of gold region = π r₁² = π(10.5)² = 346.5 cm²

Now, it is given that each of the other bands is 10.5 cm wide,

So, the radius of 2^nd circle, r₂ = 10.5cm+10.5cm = 21 cm

Thus,

∴ Area of red region = Area of 2^nd circle − Area of gold region = (πr₂²−346.5) cm²

= (π(21)² − 346.5) cm²

= 1386 − 346.5

= 1039.5 cm²

Similarly,

The radius of 3^rd circle, r₃ = 21 cm+10.5 cm = 31.5 cm

The radius of 4^th circle, r₄ = 31.5 cm+10.5 cm = 42 cm

The Radius of 5^th circle, r₅ = 42 cm+10.5 cm = 52.5 cm

For the area of n^th region,

A = Area of circle n – Area of circle (n-1)

∴ Area of blue region (n=3) = Area of third circle – Area of second circle

= π(31.5)² – 1386 cm²

= 3118.5 – 1386 cm²

= 1732.5 cm²

∴ Area of black region (n=4) = Area of fourth circle – Area of third circle

= π(42)² – 1386 cm²

= 5544 – 3118.5 cm²

= 2425.5 cm²

∴ Area of white region (n=5) = Area of fifth circle – Area of fourth circle

= π(52.5)² – 5544 cm²

= 8662.5 – 5544 cm²

= 3118.5 cm²
