15) The Monotone Convergence Theorem Revisited a) Modify the proof we gave of the MCT for increasing sequences to prove the following: If {an} is a nonincreasing sequence that is bounded belovv= then {an} converges and 1im an 2 swan}. m b) Use the Monotone Convergence Theorem to prove the Comparison Theorem for Mono- tonic Sequences: Assume that {an} and {on} are nondecreasing sequences with a.\"
