Use the ratio test to determine whether E 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 On+1 = lim an 72 +00 (b) Evaluate the limit in the previous part. Enter co as infinity and -co as -infinity. If the limit does not exist, enter DNE. an+1 lim 7 100 an (c) By the ratio test, does the series converge, diverge, or is the test inconclusive? Choose
