(1 point) Use the ratio test to determine whether \sum_{n=8}^{\infty} \frac{n^2 + 2}{2^n} converges or diverges. (a) Find the ratio of successive terms. Write your answer as a fully simplified fraction. For $n \ge 8$, $\lim_{n \to \infty} \left| \frac{a_{n+1}}{a_n} \right| = \lim_{n \to \infty} \frac{}{ } (b) Evaluate the limit in the previous part. Enter $\infty$ as infinity and $-\infty$ as -infinity. If the limit does not exist, enter DNE. $\lim_{n \to \infty} \left| \frac{a_{n+1}}{a_n} \right| = \frac{}{ } (c) By the ratio test, does the series converge, diverge, or is the test inconclusive?
