To find the sum of integers between 22 and 42, we can use a formula for the sum of an arithmetic series.
The formula for the sum of an arithmetic series is given by:
S = (n/2)(first term + last term)
In this case, the first term is 22 and the last term is 42.
Using the formula, we can calculate the sum as follows:
S = (42 - 22 + 1)(22 + 42) / 2
= (21)(64) / 2
= 1344 / 2
= 672
Therefore, the sum of the integers between 22 and 42 is 672.
