Consider the two infinite series
Series I: n=1∑∞n(−1)n−1
Series II: n=1∑∞n2(−1)n
Answer the following questions about these series.
(a) Describe the difference between absolute convergence and conditional convergence for an infinite series of real numbers.
(b) Determine whether Series I converges absolutely, converges conditionally, or diverges. Provide a clear justification for your conclusion.
(c) Determine whether Series II converges absolutely, converges conditionally, or diverges. Provide a clear justification for your conclusion.
(d) Explain how your results in parts (b) and (c) illustrate the conceptual difference you stated in part (a).
