These are calculus problems:

Geometric Series: 4. Determine whether the following geometric series converge or diverge. If it converges, deter- mine it's sum. (a) > 3(0.8)"-1 n=1 (b) n=1 (c) n= 1 5. Use the n-th Term Test (a.k.a. Divergence Test) to determine whether we can conclude the given series diverges. (YES = diverges, NO = we can't conclude whether it converges or not and therefore need to try another test) ant1 (a)> 2n - 3 n=1 (b) 73+ 1 n=1 3n- + 2n + 1 (c) > 572 - 2n + 4 n=
