## Testing for Convergence: nth term, ratio, comparison

This app allows you to enter a series and test for convergence or divergence using the nth term test, the ratio test and/or the comparison test. Several things to note:
1) You may want to move the green box (where you enter the series) to see it more clearly.
2) It appears that for this app, that the series always starts at n=1.
3) YOU must choose the comparison series.
4) The slider allows you to change the number of terms displayed.
Good luck.
