Find the sum of even integers between 21 and 99.

Expert Solution
To determine

To find:

The sum of even integers between 21 and 99.

Explanation of Solution

Approach:

The expression for sum of n terms of arithmetic progression is given by,

Sn=n2[2a+(n1)d]

Here, a is the first term, d is the common difference.

The expression for nth term is given by,

an=a+(n1)d

Calculation:

The arithmetic progression formed by even integers between 21 and 99 is,

22,24,.......,96,98

The first term of arithmetic progression term is 22.

a=22

The difference between each term is 2.

d=2

Substitute 22 for a, 2 for d and 98 for an in above formula of nth term.
