sum from n=0 to infinity of 1/((n+2)n!)

n = 0 \sum \infty \frac{1}{( n + 2 ) n !}

converges

Solution steps

n = 0 \sum \infty \frac{1}{( n + 2 ) n !}

Apply Series Ratio Test:

converges

= converges

n = 1 \sum \infty \frac{2 n + 1}{6 ^{n}}

n = 0 \sum \infty \frac{4}{3 - n}

n = 0 \sum \infty \frac{1}{n ^{4} + n ^{2}}

n = 1 \sum \infty (\frac{n}{2})^{n}

k = 2 \sum \infty (- 0.35)^{k}
