The sum of three consecutive even integers is 72. Let x represent the least consecutive integer.

Arlecino [84]

The integers are x, x + 2 and x + 4

x + x + 2 + x + 4 = 72
3x + 6 = 72
3x = 72 - 6 = 66
x = 66/3 = 22

The least consecutive integer is 22
The second consecutive integer is 24
Therefore, the numbers are 22, 24 and 26
