sum from n=1 to infinity of 1/(2+n^3)

n = 1 \sum \infty \frac{1}{2 + n ^{3}}

converges

Solution steps

n = 1 \sum \infty \frac{1}{2 + n ^{3}}

Apply Series Comparison Test:

converges

= converges

n = 1 \sum \infty 1 - e^{- n}

n = 1 \sum \infty \frac{1 7 ^{n}}{n !}

n = 1 \sum \infty cos (\frac{18}{n})

n = 1 \sum \infty \frac{n ^{5}}{6 ^{n}}

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