Determine if the sequence is monotonic and if it is bounded, \[ a_{n}=\frac{(2 n+7))}{(n+4)}, n \geq 1 \] Select the correct answer below and, if necessary, fill in the answer box(es) to complete your choice. A. \( \left(a_{n}\right) \) 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.) B. \( \left(a_{n}\right\} \) is monotonic because the sequence is nonincreasing. The sequence has a least upper bound of but is unbounded because it has nolower bound. (Simplify your answer.) C. \( \left\{a_{n}\right\} \) is not monotonic. The sequence is bounded by a lower bound of and upper bound of (Simplify your answers.) D. \( \left(a_{n}\right\} \) is not monotonic. The sequence is unbounded with no upper of lower bound.
