Good afternoon, can you help me with those questions. No need explanation

1 - 1 converges or diverges. If it converges, find its sum. Determine whether the series M n= 0 Select the correct choice below and, if necessary, fill in the answer box within your choice. 31 - O A. The series diverges because lim - + 0 or fails to exist. O B. The series diverges because it is the difference between two geometric series, at least one with |r| 21. 30 O c, The series converges because lim = 0. The sum of the series is (Type an integer or a simplified fraction.) The series converges because it is the difference between two geometric series, each with (r)
