Sequences and Series

In sequences and series, you are given a set if numbers in which you must find a pattern that separates the numbers apart. There are two different ways we can identify these sequences. The first is the arithmetic sequence which is separated by addition or subtraction meaning there is a common difference within the pattern that separates the numbers in the set. The second way is the geometric sequence that is separated through division or multiplication meaning that within the sequence, the terms are separated by a common ratio. You find the difference or ratio and you can solve any equation by simply increasing or decreasing from the first/previous term with the term that separates the numbers from each other.
