I'm thinking about a series 22:1 ak. I'm not going to tell you what the terms of my series are, but I am going to tell you that the nth partial sum of my series is given by the formula 371 = 1 + 21;. Determine whether the series 2L1 ak converges or diverges, and if it converges, nd its sum. Converges to positive innity Converges to O Converges to 2 Diverges Converges to 1 Converges' but we cannot tell what it converges to Determine whether the series _ _] COS ( ) - cos k+1 converges or diverges, and if it converges, find its sum. Converges to -2 Converges to 2 O Converges to O O Converges to O Converges, but we cannot tell what it converges to O DivergesWhat conclusion can we make by using the Test for Divergence on the series 22:2 Milk ? Converges Converges to O Diverges 1 21112 Converges to The Test for Divergence offers no conclusion
