Question

Find the sum of all integers from 1 to 500 which are divisible by 2 as well as of 5..​

Answer 1

Answer:

We know that,

Let the number of terms in this AP = n.

Sn = (n/2) [a + an], here an is the last term, which is given]

Therefore, sum of those integers between 1 and 500 which are multiples of 2 as well as of 5 = 12250.
