12-108.
1. Consider the infinite series below. For each series, decide if it diverges, converges conditionally, or converges absolutely and justify your conclusion. State the test you used. Homework Help ✎

$=\sum_{n=1}^\infty \frac{1}{n^2+2}$

$=\sum_{n=1}^\infty \frac{1}{n^3+1}$

$= \ln(1)-\ln(2)+\ln(2)-\ln(3)+\ln(3)-\ln(4)+...$

Think of this as two separate series:

$\frac{-2}{1}+\frac{-2}{3}+\frac{-2}{5}+...\frac{1}{1}+\frac{1}{2}+\frac{1}{3}+...$
