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

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

diverges

Solution steps

n = 1 \sum \infty \frac{n}{2 n}

Apply the constant multiplication rule:

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

= \frac{1}{2} \cdot n = 1 \sum \infty \frac{n}{n}

Simplify

= \frac{1}{2} \cdot n = 1 \sum \infty 1

Every infinite sum of a non-zero constant diverges

= \frac{1}{2} diverges

= diverges
