# Detecting series divergence automatically

I'm writing an interact to let my students see graphs of sequences and of sequences of partial sums. But, I also want the interact to print the sum of the infinite series, if it converges.

Is there a way I can detect whether the sum converges within the interact? I need some automation here. I don't see that the "sum" command returns any sort of error value that flags whether the series converges or not. It just produces lots of errors.

Thanks!
