### Telescoping Series Problems

In the following exercises, you are tasked with finding a formula for the nth term of the sequence of partial sums \(\{S_n\}\) for each telescoping series. After determining the formula, evaluate \(\lim_{n \to \infty} S_n\) to find the series' value or determine if it diverges.
