    Testing convergence of a series.

    Determine which tests can be used to show convergence or divergence.



    It converges via the integral test, any others? Can someone please post steps on how the integral is supposed to be done? Thanks.

    Use the comparison test. The following inequality might be useful:

    8n^3 + 6n^2 - 7 > 8n^3 + 6n^2 - 7n^2 = 8n^3 - n^2 > 8n^3 - n^3 = 7n^3
