sum from n=0 to infinity of 2/(9-n)

n = 0 \sum \infty \frac{2}{9 - n}

diverges

Solution steps

n = 10 \sum \infty \frac{2}{9 - n}

Apply the constant multiplication rule:

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

= 2 \cdot n = 10 \sum \infty \frac{1}{9 - n}

Factor

9 - n : - (- 9 + n)

= 2 \cdot n = 10 \sum \infty \frac{1}{- ( - 9 + n )}

Apply the constant multiplication rule:

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

= 2 (- n = 10 \sum \infty \frac{1}{- 9 + n})

Apply Series Comparison Test:

diverges

= 2 (- diverges)

= diverges
