    An integer has to be either even or odd

    Even numbers are numbers divisible by 2, while odd numbers are not

    Let us represent the 2 even numbers like this

    ax+1

    bx+1

    When you add the two numbers together, you get

    2a + 1 + 2b + 1

    This can be simplified using the inverse of distributive property

    2(a+b) + 2

    2(a+b+1)

    This is the sum, which is divisible by 2
