sum from n=1 to infinity of 2/(5^{n+2)}

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

converges

Solution steps

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

Apply the constant multiplication rule:

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

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

Apply Series Ratio Test:

converges

= 2 converges

= converges

\frac{d}{d x} (\frac{e ^{x^{2}} + 3 e ^{x}}{e ^{x}})

\int \frac{5 x}{2 - x ^{4}} d x

\int \frac{ln ( t )}{t ^{3}} d t

\int sech^{2} (x) tanh (x) d x
