I just took a calc 2 test and got 3/8 points on several problems that asked you to show convergence or divergence. The reason being that I didn't use the correct test of convergence? The answer was right, if you get to the point where you know the series converges, then why does it matter which test I used?(adsbygoogle = window.adsbygoogle || []).push({});

Does anyone have any tips for how to tell which test I should be using when I look at a sequence or series? (my idea is- when in doubt, use ratio test).
