What is the least of these integers?
A . C17
B . C19
C . C21
D . C23
E . C25

Answer: E

Explanation:

If the average of five consecutive odd integers is C21, then the third integer must be C21. The two larger integers are C19 and C17 and the two lesser integers are C23 and C25. C25 is the least of the five integers. Remember, the more a number is negative, the less is its value.
