Raabe's Test for Convergence of Series

We prove Raabe's Test for the convergence of infinite series. This is a more general result than the Ratio Test and works in some cases when the Ratio test is inconclusive. This is one of a general type of ratio-comparison tests. We give an example of where Raabe's Test proves convergence while the Ratio Test is inconclusive. #mikethemathematician, #mikedabkowski, #profdabkowski
