The average of four consecutive odd numbers is 24. The largest number is?
- 20
- 27
- 36
- 45
Explanation
Let's denote the four consecutive odd numbers as x, x + 2, x + 4, and x + 6.The average is 24, so:
(x + x + 2 + x + 4 + x + 6) / 4 = 24
(4x + 12) / 4 = 24
4x + 12 = 96
4x = 84
x = 21
The largest number is x + 6 = 21 + 6 = 27.
