This makes such series easy to analyze. In this video, we use partial fraction decomposition to find sum of telescoping series. Telescoping series is a series where all terms cancel out except for the first and last one. But either way

Infinite Series Chapter 1: Sequences and series Section 4: Telescoping series Page 3 Summary Some special series can be rewritten so that their partial sums simplify to expressions whose
