Use the limit comparison test to determine whether converges or diverges. (a) choose a series with terms of the form and apply the limit comparison test. write your answer as a fully reduced fraction. for , 1/n^7 (b) evaluate the limit in the previous part. enter as infinity and as -infinity. if the limit does not exist, enter dne. = (c) by the limit comparison test, does the series converge, diverge, or is the test inconclusive?
