Answer:
Any even number can be represented in form 2n, where n is an integer number. So let’s consider two even numbers, say, 2m and 2n, where m and n are integers. Then we have 2m + 2n = 2 (m+n). The number 2(m+n) can be divided by 2, therefore, it is even. Hence, the sum of any two even numbers is an even number.
