**Question 2**
If the average (arithmetic mean) of 5 consecutive integers is 11, what is the sum of the least and greatest of the 5 integers?

- 23
- 22
- 21
- 20
- 19

The correct Answer is

**22** and the correct

**Choice is (B)**.

The arithmetic mean of 5 consecutive integers is the 3rd integer or the middle number.

Therefore, if a1, a2, a3, a4 and a5 are the five consecutive integers, then a3 = 11

Hence, a1 = 9 and a5 = 13

Sum of the least and the greatest integer = a1 + a5 = 9 + 13 = 22.

Choice (B).
