**Week 16: Infinite Series**

In mathematics, a series is, roughly speaking, a description of the operation of adding infinitely many quantities, one after the other, to a given starting quantity. The study of series is a major part of calculus and its generalization, mathematical analysis. "Series" sounds like it is the **list of numbers**, but it is actually when we add them together.A **finite series** is a summation of a **finite** number of terms. An **infinite series** has an **infinite** number of terms and an upper limit of **infinity**.
