Finite series

A finite series is a sequence of terms added together, where the number of terms is limited or counts to a specific number. Think of it as summing a set of numbers that ends after a certain point, like adding the scores from a game over a fixed number of rounds. For example, adding the first five numbers: 1 + 2 + 3 + 4 + 5. Finite series are useful for calculating totals where the process stops after a known number of steps, and they often have formulas that help find the sum efficiently without adding each term individually.
