Hello, I understand the Limit Comparison Test, but how do you know what you should compare your series to?
Like for you should compare it to
of which I know diverges so with the L.C.T it will probably diverge. But why is it that you would compare it to 1/n, how do you figure out what you should compare it to? Is it because n/n^2 gives you 1/n or?
Thanks,
Matt
