13. Does the series X∞ n=0 (−1)n 1 √ n2 +1 converge absolutely, converge conditionally, or diverge? Answer: The terms √ 1 n2+1 are decreasing and go to zero (you should check this), so the Alternating Series Test says that the series converges. To see that the series does not converge absolutely, it suffices to show that the series X∞ ...

Problem 1: Find the 10 th term of the arithmetic sequence where the first term a 1 is 5 and the common difference d is 3. Solution: Using the formula for the nth term of an arithmetic sequence: a n = a 1 + (n - 1)d. For the 10th term (\(n = 10\)): a 10 = 5 + (10-1) × 3

Limit Comparison Tests to determine if an infinite series converges or diverges. In order to use either test the terms of the infinite series must be positive. Proofs for both tests are also given. Alternating Series Test – In this section we will discuss using the Alternating Series Test to determine if an infinite series converges or diverges.
