Solution steps

n = 1 \sum \infty \frac{1}{3 ^{n + 1}}

Apply Series Ratio Test:

converges

= converges

n = 1 \sum \infty \frac{1}{2 n}

x = 0 \sum \infty \frac{1}{5 ^{x}}

n = 1 \sum \infty \frac{1}{1. 1 ^{n}}

k = 1 \sum \infty \frac{1}{16 k ^{2} - 4}

n = 1 \sum \infty \frac{n}{n ^{2} - 2 n + 5}
