Determine if the sequence is monotonic and if it is bounded. 5ngn nl an = n≥1 Select the correct answer below and, if necessary, fill in the answer box(es) to complete your choice. A. {a} is not monotonic. The sequence is unbounded with no upper or lower bound. B. {a} is not monotonic. The sequence is bounded by a greatest lower bound of and a least upper bound when n = C. {a} is monotonic because the sequence is nondecreasing. The sequence has a greatest lower bound of (Simplify your answer.) (Simplify your answers.) but is unbounded because it has no upper bound. D. {a} is monotonic because the sequence is nonincreasing. The sequence has a least upper bound when n = (Simplify your answer.) but is unbounded because it has no lower bound.
