Determine whether the following series converges. E 5( - 1) K+ 1 K 7 K = 1Let ax 2 0 represent the magnitude of the terms of the given series. Identify and describe ak Select the correct choice below and fill in any answer box in your choice O A. ak = and for any index N, there are some values of k > N for whichrak + 1 2 ak and some values of k > N for which ak + 1 Sak. O B. ak = is nondecreasing in magnitude for k greater than some index N. O c. ak= is nonincreasing in magnitude for k greater than some index N. lim ak = K -+ 00Does the series converge? O Yes O No
