# Arithmetic Sequence and Series Word Problems?

A sequence is a set of numbers that are written in a particular order. An arithmetic series is the sum of the terms in an arithmetic sequence with a definite number of terms. The number added to each term is called a constant because it is always the same. The fixed amount is called the common difference. To find the common difference, you must subtract the first term from the second term. With arithmetic sequence and series word problems, two separate formulas are used to find the solution.
