Let a, = (n+ 1e for n21,Then which of the followings is/are not true for the sequence {a,}? {a,}is unbounded 1. 2. a,}is bounded but does not converge. 3 bounded and converge to 1. bonded and converge to 0. 4. Your Answer: 2,3,44 Correct Answer: 1,2,3 I can't figure out by logarithm test, please explain....
