Its good to keep in mind the definition of Monotone sequence and bounded sequence.

A sequence is:

(a)increasingif and only if for any

(b)decreasingif and only if for any

The sequence isMONOTONEif eitheroneof these properties holds.

So check for the terms in you sequence, and you'll be able to find out if its monotone or not!

The sequence isBOUNDED ABOVEif there exists a number M such that for any . M is called the upper bound.

The sequence isBOUNDED belowif there exists a number m such that for any . m is called the lower bound.
