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

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

diverges

Solution steps

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

Apply Series Divergence Test:

diverges

= diverges

n = 1 \sum \infty \frac{n}{n + 7}

n = 0 \sum \infty 2 (3)^{n}

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

n = 0 \sum \infty n^{3} (- 1)^{n}

n = 1 \sum \infty \frac{5}{e ^{n}}
