sum from n=1 to infinity of 8ln(n/(n+1))

n = 1 \sum \infty 8 ln (\frac{n}{n + 1})

diverges

Solution steps

n = 1 \sum \infty 8 ln (\frac{n}{n + 1})

Apply the constant multiplication rule:

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

= 8 \cdot n = 1 \sum \infty ln (\frac{n}{n + 1})

Apply log rule:

lo g_{c} (\frac{a}{b}) = lo g_{c} (a) - lo g_{c} (b)

ln (\frac{n}{n + 1}) = ln (n) - ln (n + 1)

= 8 \cdot n = 1 \sum \infty ln (n) - ln (n + 1)

Expand telescoping series:

diverges

= diverges

n = 0 \sum \infty 5 \cdot (\frac{1}{4})^{n}

n = 0 \sum \infty \frac{n}{n !}

n = 4 \sum \infty \frac{1}{n} - \frac{1}{n + 3}

n = 1 \sum \infty \frac{e ^{n}}{n ^{4}}

n = 1 \sum \infty \frac{4}{n ^{2} + 4 n + 3}
