The sum of three consecutive even numbers is 72. What is the smallest number?
- 28
- 22
- 24
- None of these
Explanation
Let's denote the three consecutive even numbers as x, x + 2, and x + 4.
Given:
x + (x + 2) + (x + 4) = 72
Combine like terms:
3x + 6 = 72
Subtract 6 from both sides:
3x = 66
Divide by 3:
x = 22
The smallest number is 22.
