sum from n=0 to infinity of ((-1)^n)/2

n = 0 \sum \infty \frac{( - 1 ) ^{n}}{2}

diverges

Solution steps

n = 0 \sum \infty \frac{( - 1 ) ^{n}}{2}

Apply the constant multiplication rule:

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

= \frac{1}{2} \cdot n = 0 \sum \infty (- 1)^{n}

Apply Series Geometric Test:
