30th= ? a=10 n=30 d=a2-a3=7-10= -3 an= a+(n-1)d = 10+(30-1)(-3) = 10+29(-3) = 10-87 = -77 a30= -77

Aryan Mishra 5 years, 6 months ago

30th term=? a=10 n=30 d= a2-a1= 7-10= -3 an=a+(n-1)d = 10+(30-1)(-3) = 10+29(-3) =10-87 = -77 a30= -77

Gaurav Seth 5 years, 6 months ago

C) -77

Given AP = 10,7,4 find 30th term ??

a = 10 n = 30 d = T2-T1 = 7-10 = -3

Tn = a+(n-1)d

⇒ 10+(30-1)-3

⇒ 10+ 29 × (-3)

⇒ 10 - 87 = -77

T30 = -77..

Yogita Ingle 5 years, 6 months ago

Let positive integer a = 4m + r , By division algorithm we know here 0 ≤ r < 4 , So
When r = 0
a = 4m
Squaring both side , we get
a² = ( 4m )²
a² = 4 ( 4m²)
a² = 4 q , where q = 4m²

When r = 1
a = 4m + 1
squaring both side , we get
a² = ( 4m + 1)²
a² = 16m² + 1 + 8m
a² = 4 ( 4m² + 2m ) + 1
a² = 4q + 1 , where q = 4m² + 2m

When r = 2
a = 4m + 2
Squaring both hand side , we get
a² = ( 4m + 2 )²
a² = 16m²+ 4 + 16m
a² = 4 ( 4m² + 4m + 1 )
a² = 4q , Where q = 4m² + 4m + 1

When r = 3
a = 4m + 3
Squaring both hand side , we get
a² = ( 4m + 3)²
a² = 16m² + 9 + 24m
a² = 16m² + 24m + 8 + 1
a² = 4 ( 4m² + 6m + 2) + 1
a² = 4q + 1 , where q = 4m² + 6m + 2
Hence
Square of any positive integer is in form of 4q or 4q + 1 , where q is any integer.
