Sum of the first 120 even numbers

The first 120 even numbers range from 2 to 240. On this page, we will show you how to calculate the first 120 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 120 into our formula, we get the following:

120 × (120 + 1)
= 14520

Therefore, the sum of the first 120 even numbers is 14520.
