74, 76 and 78

Explanation:

Let the first of your integers be x.

As you are only looking at even integers, the next consecutive even integer would be x + 2 and the consecutive even integer after that would be x + 4.

You know that their sum is 228, so you have

x + (x+2) + (x + 4) = 228

<=> color(white)(xxx) x + x + 2 + x + 4 = 228

<=>color(white)(xxxxxxxxxxx) 3x + 6 = 228

Subtract 6 from both sides of the equation:

<=> 3x = 222

Divide by 3 on both sides of the equation:

<=> x = 74

Thus, your consecutive even integers are 74, 76 and 78.
