Problem

Consider the three infinite series below. I. ∑n=1∞(35)n\displaystyle \sum_{n=1}^{\infty} \left(\dfrac{3}{5}\right)^{n} II. ∑n=0∞(−1)n(23)n\displaystyle \sum_{n=0}^{\infty} (-1)^{n}\left(\dfrac{2}{3}\right)^{n} III. ∑n=1∞1n\displaystyle \sum_{n=1}^{\infty} \dfrac{1}{n} For each series, analyze its behavior and provide clear reasoning in your responses. a. Determine whether each series converges or diverges. Provide a concise justification for every conclusion you reach. b. For every convergent series, state whether it is geometric or non-geometric and justify your classification based on the form of its terms.
