By using Euclid's division lemma a=bq+r where 0<=r136 170 =136×1+34 136 =34×4+0 So, HCF of 136 & 170 is 34 Now,255 and 34 255 >34 255=34×7+17 34=17×2+0 So,HCF of 255 & 34 is 34 Therefore, HCF of 136,170 and 255 is 34

ANSWER

The first term of an ap is 5 and the last term is 45 and the sum is 400. Find the number of terms and common differences.

Posted by Bharath Kori 6 years, 5 months ago

Sia ? 6 years, 5 months ago

Here, a = 5
l = 45
S = 400
We know that
{tex}S = \frac{n}{2}(a + l){/tex}
{tex} \Rightarrow 400 = \frac{n}{2}(5 + 45){/tex}
{tex} \Rightarrow 400 = \frac{n}{2}(50){/tex}
{tex} \Rightarrow 400 - 25n{/tex}
{tex} \Rightarrow n = \frac{{400}}{{25}}{/tex}
{tex} \Rightarrow n = 16{/tex}
Hence, the number of terms is 16.
Again, we know that
l = a + (n - 1)d
{tex} \Rightarrow {/tex} 45 = 5 + (16 - 1)d
{tex} \Rightarrow {/tex} 45 = 5 + 15d
{tex} \Rightarrow {/tex} 40 = 15 d
{tex} \Rightarrow d = \frac{{40}}{{15}} = \frac{8}{3}{/tex}
Hence, the common difference is {tex}\frac{8}{3}{/tex}.
