In this article, we will discuss the program to find the sum of even numbers in different programming languages.

But before writing the programs, let's first see a brief description of even numbers and the formula to find the sum of even numbers.

### Even numbers

Any integer number that is completely divided by 2 is known as the even number. All the even numbers must be divided by 2. To check whether the given integer number is an odd number or an even number; we have to check the number's last digit. The even numbers always end with the last digit of 0, 2, 4, 6, and 8.

## Sum of even numbers

It is easy to find the sum of even numbers from 2 to infinity. It can be obtained by using the formula for finding the sum of natural numbers or by using the arithmetic progression.

We can use the formula n(n+1) to find the sum of even numbers, where n is any natural number. For instance, if we have to find the sum of the first four even numbers 2, 4, 6, and 8, the value of n will be 4.

i.e. sum of first four even numbers = 2 + 4 + 6 + 8 = 20

or, = 4(4+1) = 4 * 5 = 20 (n = 4)

If we have to find the sum of first three even numbers that are 2, 4, and 6, then the value of n will be 3. So,

3(3+1) = 12

Or, 2 + 4 + 6 = 12
