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

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

diverges

Solution steps

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

Apply Series Integral Test:

diverges

= diverges

n = 1 \sum \infty (\frac{2}{n})^{4}

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

n = 0 \sum \infty n^{^{'}} + n

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

n = 1 \sum \infty n! (- e)^{- n}
