Question 02 (c) (iv)
For each of the following series, choose the appropriate statement. (Write N, O, P, S, or T in each box; each answer will be used at most once, and each series matches a single answer only.)
N: The series converges by the Ratio Test.
O: The series converges absolutely by the Comparison Test with a p-series.
P: The series converges by the Alternating Series Test.
S: The series diverges.
T: The series converges by the Integral Test.
Make sure you understand the problem fully: What is the question asking you to do? Are there specific conditions or constraints that you should take note of? How will you know if your answer is correct from your work only? Can you rephrase the question in your own words in a way that makes sense to you?
If you are stuck, check the hint below. Consider it for a while. Does it give you a new idea on how to approach the problem? If so, try it!
Look for an upper bound on the terms of the series that will make it easier to work with.
Checking a solution serves two purposes: helping you if, after having used the hint, you still are stuck on the problem; or if you have solved the problem and would like to check your work.

Please rate my easiness! It's quick and helps everyone guide their studies.
First note that
So our series absolutely converges if the larger series converges by Comparison test.
Indeed, we can show that the series converges applying p-series test because of .
Thus the answer is .
