an =
n21
Select the correct answer below and, if necessary, fill in the answer box(es) to complete your choice.
OA. (an) is not monotonic. The sequence is bounded by a greatest lower bound of and a least upper bound
when n = (Simplify your answers.)
OB. (an) is monotonic because the sequence is nonincreasing. The sequence has a least upper bound when n =
but is unbounded because it has no lower bound.
(Simplify your answer.)
OC. (an) is monotonic because the sequence is nondecreasing. The sequence has a greatest lower bound of
but is unbounded because it has no upper bound.
(Simplify your answer.)
OD. (an) is not monotonic. The sequence is unbounded with no upper or lower bound.
