Extracted text: For the following alternating series: a) Apply the Alternating Series Test (AST) to prove convergence or divergence; b) If convergent, prove whether it is converges absolutely or converges conditionally; c) If convergent, evaluate the 4th partial sum S4, to 3 decimals, provide the upper bound on the remainder, and use that bound to provide an interval which contains the actual sum S:
