By now you should understand that a sequence is a series or grouping of things arranged in a specific order and in math, it refers to a series of arranged numbers. There are two sequences – the arithmetic sequence and the geometric sequence.

In the arithmetic sequence there exists a constant number that is either added to or subtracted from each number in the series. In the geometric sequence, you have a constant number that is multiplied to each of the numbers in the series.
In order to do this quiz, please first check out the quizzes on Arithmetic Sequence and Geometric Sequence. These quizzes will help you to understand the process of determining the sequence.
Doing number sequences is not hard but it does take some concentration to first determine the constant number and then to remember which sequence you are working with.
