Determine whether the following series converges.
2-1)k+1 In k
k = 1
Let ak >U represent the magnitude of the terms of the given series. Identify and describe a.
Select the correct choice below and fill in any answer box in your choice.
O A. The series diverges because ak
is nonincreasing in magnitude for k greater than some index N and lim a
O B. The series converges because ak =
and for
index N, there are some values of k> N for which a1 za, and some values of k>N for which a+1sak.
