Question
Each of the following statements is an attempt to show that a given series is convergent or divergent using the Comparison Test (NOT the Limit Comparison Test) For each statement, enter C (for 'correct') if the argument is valid, or enter (for "incorrect") if any part of the argument is flawed. (Note: if the conclusion is true but the argument that led to it was wrong you must enter I
