sum from n=1 to infinity of 1/(n^2+25)

n = 1 \sum \infty \frac{1}{n ^{2} + 25}

converges

Solution steps

n = 1 \sum \infty \frac{1}{n ^{2} + 25}

Apply Series Comparison Test:

converges

= converges

n = 4 \sum \infty (- 0.61)^{n}

n = 1 \sum \infty n (\frac{1}{3})^{n}

k = 1 \sum \infty \frac{k}{e ^{6 k}}

n = 1 \sum \infty \frac{n}{10 n - 3}

n = 0 \sum \infty 5 (\frac{5}{2})^{n}
