Mathematical series

A mathematical series is the sum of the terms of a sequence of numbers. It represents the process of adding individual terms together to obtain a total. Series are often denoted using summation notation with the sigma symbol (Σ). ### Key Concepts: 1. **Sequence**: A sequence is an ordered list of numbers. For example, the sequence of natural numbers can be written as \(1, 2, 3, 4, \ldots\).
