Series | Ratio Test: Another Full Example

The video tutorial explains how to determine the convergence of a series using the ratio test. It begins by introducing the series and the criteria for convergence. The instructor defines a sub n and calculates a sub n plus 1, then applies the ratio test to find the limit. The expression is simplified, and the limit is evaluated to conclude that the series converges absolutely.

What does the ratio test state about the limit L?

What is the final value of the limit L and what does it indicate about the series?

Summarize the conclusion drawn about the convergence of the original series.
