Infinite sum

A series is a group of several things that are all about the same thing, or are intentionally similar.

In mathematics, a series is the adding of a never ending mathematical sequence (a list of numbers). For example:

The dots mean that the adding does not have a last term, but goes on to infinity.

If the result of the addition gets closer and closer to a certain limit value, this is the sum of the series.

This series will have 2 as its sum. However, not all series have a sum.
