The first 125 even numbers range from 2 to 250. On this page, we will show you how to calculate the first 125 positive even whole numbers by using our formula.

The formula to calculate the sum of even numbers is: sum = n × ( n + 1) where n is the even numbers. When we enter 125 into our formula, we get the following:

125 × (125 + 1)
= 15750

Therefore, the sum of the first 125 even numbers is 15750.
