Answer 2

Step-by-step explanation:

Answer:

Given:

sum of all odd natural numbers from 1 to 50

series will be 1,3,5,7,...........49

Formula:

$sn = \frac{n}{2} (2a + (n - 1)d$

Now, put the given values .....

$sn = \frac{n}{2} (2a + (n - 1)d$

$in \: series \: a = 1$

$and \: d = 3 - 1 = 2$

$s50 = \frac{n}{2} (2(1) + (n - 1)2$

$s50 = \frac{50}{2} (2 + (50 - 1)2$

$s50 = 50(2 + 49)2$

$s50 = 25(51)2$

s50=625

solve this u get urs answer perfectly
