Think back on the Font Tester App. Can you think of an example of another app or feature of an app which would use a loop to control different elements on a screen?

Consider the series where in this problem you must attempt to use the ratio test to decide whether the series converges. compute enter the numerical value of the limit l if it converges, inf if it diverges to infinity, minf if it diverges to negative infinity, or div if it diverges but not to infinity or negative infinity.
