A Series is defined as the sum of the terms of a sequence,those terms are added together.

To indicate a series, we use summation or sigma symbol $\sum$ . Generally,series can be written in the following form:
                           $\sum_{n=1}^{k}S_{i}$$=S_{1}+S_{2}+S_{3}+....+S_{k}$

 where,$S_{i}$ denotes $i^{th}$ term of a series

Series can be finite and infinite. Finite series is a sum of a finite number of terms. An infinite series is sum of infinite number of terms with upper limit of infinity.
Below you could see the steps

Step 1: Note down the range of the given function.
Step 2: Solve the function for all the values for the given range.
Step 3: Add all the values to get the final answer.
