Question

The sum of three consecutive even numbers is 90. What is the smallest of these numbers

Answer 1

The smallest number is 28

Answer 2

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
