a. Find a formula for the general term . b. Does this sequence converge or diverge? Why? c. Does the series converge or diverge? Why?
I did part (a) already since it was the easiest one and I got a_n=3/(4n). correct me if I am wrong. However, I do not know which test to use for part b and c.

Does the series (-1)" (n + 2)" ? converge absolutely, converge conditionally, or diverge? (5n)" Choose the correct answer below and, if necessary, fill in the answer box to complete your choice O A. The series converges absolutely because the limit used in the Root Test is OB. The series diverges because the limit used in the nth-Term Test is different from zero, OC. The series converges conditionally per the Alternating Series Test and because the limit used in the...

Does the series (-1)"+1 n n+1 converge absolutely, converge conditionally, or diverge? n=1 Choose the correct answer below and, if necessary, fill in the answer box to complete your choice. OA. 1 The series converges conditionally per Alternating Series Test and the Comparison Test with n + 1 n = 1 O B. The series diverges because the limit used in the Ratio Test is not less than or equal to 1. OC. The series converges conditionally per the Alternating...
Please include answer letter Does the series Σ converge or diverge? 1+ 2 n=1 Choose the correct answer below. O A. The series diverges because it is a p-series with p s 1. OB. The integral test shows that the series diverges. OC. The nth-term test shows that the series diverges. OD. The integral test shows that the series converges. O E. The series converges because it is a p-series with p > 1. Click to select your answer.
