2 Arithmetic Series Arithmetic series are ones that you should probably be familiar with. As a reminder, in an arithmetic sequence or series the each term di ers from the previous one by a constant. An example of an arithmetic sequence is 1;3;5;7;9;:::. Theorem 1 (Gauss). Let S denote the sum of the terms of an n-term arithmetic sequence with ...

The n-th partial sum of a series is the sum of the first n terms. The sequence of partial sums of a series sometimes tends to a real limit. If this happens, we say that this limit is the sum of the series. If not, we say that the series has no sum. A series can have a sum only if the individual terms tend to zero. But there are some series
