Question 1. For each of the following series, determine if they are conditionally convergent, absolutely convergent, or divergent. (a) Vn + 1 = (-1)^(n+1) / (n - 1), n = 1 (b) Vn = 2(-1)^(999n + 1000), n = 1 (c) Vn = 2^n, n = 1

Step 1
This is an alternating series, so we can apply the Alternating Series Test. We have $a_n = \frac{1}{n}$, which is positive, decreasing, and $\lim_{n\to\infty} a_n = 0$. Show more…

Question 1: Determine whether the series is convergent or divergent by using the specified approach. a) sum_{n=1}^{infty} frac{n!}{10^n} (Ratio test) b) sum_{n=1}^{infty} (frac{-3n}{1 + 2n})^{4n} (Root test) c) sum_{n=1}^{infty} frac{1}{1 + n^2} (Comparison Test)
