3 consecutive even numbers : x, x + 2, x + 4
x + x + 2 + x + 4 = 90
3x + 6 = 90
3x = 90 - 6
3x = 84
x = 84/3
x = 28 <== smallest one
x + 2 = 28 + 2 = 30
x + 4 = 28 + 4 = 32
x + x + 2 + x + 4 = 90
3x + 6 = 90
3x = 90 - 6
3x = 84
x = 84/3
x = 28 <== smallest one
x + 2 = 28 + 2 = 30
x + 4 = 28 + 4 = 32
