Consecutive integer questions typically tell you the sum total of a group of consecutive integers and then ask you to find one of these integers.
To handle sum of consecutive integer questions:
- First divide the sum by the number of integers to get the midpoint of the sequence.
- Then count up or down from this midpoint to find the integer asked for by the question.
Example:
The sum of five, consecutive odd integers is 195. What is the greatest of these integers?
(A) 33
(B) 36
(C) 39
(D) 43
(E) 71
