Use the ratio test to determine whether M8 8" n=7 (2n)2 converges or diverges. (a) Find the ratio of successive terms. Write your answer as a fully simplified fraction. For n 7, lim nx An+1 An = lim n (b) Evaluate the limit in the previous part. Enter as infinity and -o as -infinity. If the limit does not exist, enter DNE. lim n An+1 an (c) By the ratio test, does the series converge, diverge, or is the test inconclusive? Choose
