## Definitions

** Consecutive integers** are integers that follow one another with a difference of 1. There are other types of consecutive patterns or

**, such as even integers where the difference between consecutive even integers is 2. Two common question types about sequences of consecutive integers are the number of items in the sequence and the sum of the sequence.**

*sequences*4, 6, 8, 10 difference = 2: consecutive even integers

3, 5, 7, 9, 11, 13 difference = 2: consecutive odd integers

3, 5, 7, 11, 13 difference varies: consecutive prime numbers

10, 15, 20, 25 difference = 5: multiples of 5
