SAT Math: Sum of Consecutive Integers

Adam — Mon, 03 Mar 2008 12:30:06 +0000

Consecutive Integers are those which occur in numerical order. (like 3,4,5,6,…) One type of consecutive integer question tells you the sum total of a group of consecutive integers and asks you to find one of these integers.

To answer Sum of Consecutive Integer questions: 1. Divide the sum total by the number of integers to find the midpoint of the sequence. 2. Then count up or down from this midpoint to find the integer asked for by the question.

Example: Answer and explanation below.
