sum from n=0 to infinity of 3/(5^{n+2)}

n = 0 \sum \infty \frac{3}{5 ^{n + 2}}

converges

Solution steps

n = 0 \sum \infty \frac{3}{5 ^{n + 2}}

Apply the constant multiplication rule:

\sum c \cdot a_{n} = c \cdot \sum a_{n}

= 3 \cdot n = 0 \sum \infty \frac{1}{5 ^{n + 2}}

Apply Series Ratio Test:

converges

= 3 converges

= converges

n = 1 \sum \infty \frac{e}{π ^{n}}

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

n = 1 \sum \infty n e^{2 n}

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

n = 0 \sum \infty (\frac{n + 5}{n})^{n}
