Determine whether the alternating series > (- 1)n+1 4 5 Inn converges or diverges. n = 2 . . . Let up 2 0 represent the magnitude of the terms of the given series. Identify and describe un . Select the correct choice below and fill in any answer box in your choice. O A. Un = is nondecreasing in magnitude for n greater than some index N. OB. Un= is nonincreasing in magnitude for n greater than some index N. Un= and for any index N, there are some values of n > N for which un + 1 2 up and some values of n > N for O C. which un + 1 Sun
