What are "consecutive integers"?

Consecutive integers are two integers that sit adjacent to each other in a number sequence. An integer is a positive or negative whole number. The lowest value set of positive consecutive integers are 1 and 2, and the highest value set of negative integers are -1 and -2.

A series or grouping of consecutive integers means each number in the set is adjacent to exactly one other integer. In a set with numbers 3, 4, 5, 6 and 7, each number is tangent to exactly one other integer. One of the first math skills preschool children learn is to count the consecutive integers from 1 to 10.
