Sum of the first 100 even numbers

The first 100 even numbers range from 2 to 200. On this page, we will show you how to calculate the first 100 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 100 into our formula, we get the following:

100 × (100 + 1)
= 10100

Therefore, the sum of the first 100 even numbers is 10100.

Be aware that we consider 2 to be the first positive even number. If you consider 0 to be the first positive even number, then the answer to the sum of the first 100 even numbers would be 9900.

Note that the sum of the first 100 even numbers is not the same as the sum of all even numbers up to 100. The sum of all even numbers from 1 to 100 inclusive is 2550.
