Dr. Eaton begins Arithmetic Series by highlighting the common difference between terms as well as the possibility of finite and infinite series. Then she moves into the sum of arithmetic series as well as how to deal with sigma notation. Extra examples at the end make sure you can use all the new concepts learned.
There are two formulas for the sum. Use one if you are given d and the other if you are given an. In both cases, you will be given the values of a1 and n.
In some problems, you must first use the formula for the sum and then the formula for the nth term.
