Problem 10. (1 point) Use the ratio test to determine whether (2n)2 converges or diverges. (a) Find the ratio of successive terms. Write your answer as a fully simplified fraction. For n > 9, lim an+1 lim 7+00 an (b) Evaluate the limit in the previous part. Enter oo as infinity and -oo as -infinity. If the limit does not exist, enter DNE. lim an+1 n +00 0 an (c) By the ratio test, does the series converge, diverge, or is the test inconclusive?| Choose Note: You can earn 40% partial credit for 2 - 3 correct answers. Problem 11. (1 point) Consider the power series (1lr)" The interval of convergence goes from a = to x = The radius of convergence is R = If needed, enter INF for oo and -INF for -Do.
