7 Question 7 (20 points). Determine whether the following series converge absolutely, con- verge conditionally, or diverge, and by which test: (1) E(- 1) k 7 k2 + k + 2 k 4/2 + 3 K=0 (2) [(- 1)k (k +1)23k k! HINT: part a is root test, part b is ratio test. FURTHER HINT: it is NOT possible to converge conditionally using root or ratio test
