Use the Alternating Series Test to determine whether the series converges or diverges. (For limits, enter a number, "-infnity", "infinity", or "DNE" as appropriate.) 2n5 n= 1 676 + 7 lim bn = n-+00 A. { Un is ultimately decreasing because the function J satifying J(TL) = Un is decreasing on the interval Therefore the series converges by the Alternating Series test. OB. lim an = , so the series diverges by the Divergence Test. 72-+00
