# How do I find the limit of a series?

##### 1 Answer

There is no general method to do this.

Consider the following definition considering a series of terms

This is clearly a sequence, called the sequence of *partial sums* of the series.

The question of determining the limit of the series

then becomes a question of determining the limit of a sequence:

which does not have a trivial answer.

Some limits can be determined using certain tricks, like the geometric series of initial term

or the the series
