QUESTION #8110
Question 1
If the arithmetic mean of 5 consecutive integers is 12, what is the sum of the least and greatest of these integers?
Correct Answer Explanation
For 5 consecutive integers, the mean equals the middle (3rd) integer. So the middle integer is 12.
The 5 integers are: $10, 11, 12, 13, 14$.
The least is 10 and the greatest is 14.
Sum $= 10 + 14 = 24$.
