Suppose that Cna" converges when x = -5 and diverges when x = 7. Determine whether the following series converge or diverge. Answer "Converges" or "Diverges." ? ? ? ? 1. n=0 x 2.2" n=0 3. Σ Cn(-4)" n=0 80 4.(-1)" en 12" n=0

Please solve and show all work. Thank you.

For each of the following series, tell whether or not you can apply the 3-condition test (i.e. the alternating series test). If you can apply this test, enter D if the series diverges, or C if the series converges. If you can't apply this test (even if you know how the series behaves by some other test), enter N.
