Sum of the first 11 even numbers

The first 11 even numbers range from 2 to 22. On this page, we will show you how to calculate the first 11 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 11 into our formula, we get the following:

11 × (11 + 1)
= 132

Therefore, the sum of the first 11 even numbers is 132.

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 11 even numbers would be 110.

Note that the sum of the first 11 even numbers is not the same as the sum of all even numbers up to 11. The sum of all even numbers from 1 to 11 inclusive is 30.
