Show that the Ʃ 1/(2n-1)^3 Converges
The Attempt at a Solution
I tried using the ratio the ratio test but that didn't work
I assume the summation is over all non-negative n (i.e. 1,2,3..)?
Just use the comparison test with zeta(3), which converges. If you need to establish convergence of the latter, use the integral test.
If I say 1/n^3 could I also use the p-series test.
and yes i meant the summation where n=1 to infinity
