sum from n=0 to infinity of n/(10^n)

n = 0 \sum \infty \frac{n}{1 0 ^{n}}

converges

Solution steps

n = 0 \sum \infty \frac{n}{1 0 ^{n}}

Apply Series Ratio Test:

converges

= converges

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

n = 1 \sum \infty \frac{n}{n + 4}

n = 0 \sum \infty \frac{3 ^{n}}{2}

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

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