None of these series is convergent b. $\sum_{n=1}^{\infty} \frac{1 - 2n}{3n + 1}$ c. $\sum_{n=1}^{\infty} \frac{3n + 1}{8n}$ d. $\sum_{n=1}^{\infty} \frac{3n^2 + 4}{n^2 + 1}$ Now, let's analyze each series: b. For the series $\sum_{n=1}^{\infty} \frac{1 - Show more…

(a) For what values of x does the series sum_{n=1}^{infty} frac{n}{3^n} (x - 2)^n converge? (b) Determine whether the series is absolutely convergent or conditionally convergent: sum_{n=1}^{infty} (-1)^{n-1} frac{n}{n^2+4} (c) Find the sum of the series: sum_{n=1}^{infty} (frac{1}{n(n+1)} - frac{1}{3^n})

The following series are geometric series. Determine whether each series converges or not. For the series which converge, enter the sum of the series. For the series which diverges, enter "DNE" (without quotes).
