sum from n=0 to infinity of n^2-2

n = 0 \sum \infty n^{2} - 2

diverges

Solution steps

n = 0 \sum \infty n^{2} - 2

Apply Series Divergence Test:

diverges

= diverges

n = 0 \sum \infty \frac{5 n}{10 + n}

n = 0 \sum \infty 9 n^{2} - 36 n + 35

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

n = 0 \sum \infty - 8 (- \frac{2}{3})^{n}

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