# Math Help - The integral Test...Calculus 2

1. ## The integral Test...Calculus 2

Integral Test...Calculus 2?
Use the integral test to determine the convergence or divergence of the series.

1/2 + 1/5 + 1/10 + 1/17 + 1/26 + . . .

I just need the function that can be made from the given list of numbers. I can take it from there.

Thanks. I kept thinking it was 1/(2^n + 1). I can take it from here.
