Determine whether the given series is absolutely convergent, conditionally convergent, or divergent. Support your conclusion with a well-written argument that names any series test used, shows the conditions of the series test(s) utilized are met, provides calculation(s) to show a conclusion can be made, and summarizes your findings at the end.

Be sure to provide a careful argument to prove the type of convergence and name any series tests you apply. b) What is the smallest integer N so that SN approximates the sum of the series accurate to less than 10-4? What is this approximation? c) Is the approximation given in part (b) an overestimate or an underestimate? Explain.
