If the sum of three consecutive even numbers is 42, what are the three numbers?

Let's assume that the first one is x, the second one is x + 2, and the third one is x + 4, that is, x + X + 2 + X + 4 = 42, x = 12. Then the three numbers are 12, 14, 16, that is, 42 divided by 3, and the middle number 14 can be obtained. Then the first one is 14-2 = 12, and the last one is 16
