Question

If the middle number of 25 consecutive natural numbers is 31, then the sum of all those numbers is

Answer 1

The required sum of the given 31 numbers is 775.

Step-by-step explanation:  We know that

if the middle number of n number of numbers is p, then the sum of all those n numbers is n × p.

According to the given information, we have

number of given numbers, n = 31

and

the middle number, p = 31.

Therefore, the sum of the 31 numbers is given by

$S=n\times p=31\times25=775.$

Thus, the required sum of the numbers is 775.
