Review Question 3: Geometric Series and p-Series

In this video I go over a quick review of geometric series and p-series and show the circumstances for when they are convergent. A geometric series has all the terms being a constant number multiplied by a common ratio starting from the power of 0 and incrementing by 1 for each successive term. The series is convergent and equal to the (first term) / (1 - common ratio) when the absolute value of the common ratio is less than 1. I also show a geometric interpretation of the geometric series using similar triangles.

A p-series is of the form 1/n^p and it is convergent when p is greater than 1 and divergent for all other values.

The timestamps of key parts of the video are listed below:
