Monotonic and bounded sequences  Sequence and Series
Monotonic and bounded sequences
In this section, we will be talking about monotonic and bounded sequences. We will learn that monotonic sequences are sequences which constantly increase or constantly decrease. We also learn that a sequence is bounded above if the sequence has a maximum value, and is bounded below if the sequence has a minimum value. Of course, sequences can be both bounded above and below. Lastly, we will take a look at applying theorem 7, which will help us determine if the sequence is convergent. One important to note from the theorem is that even if theorem 7 does not apply to the sequence, there is a possibility that the sequence is convergent. It's just that the theorem will not be able to show it.

Theorems:
1. A sequence is increasing if $a_n$ < $a_{n+1}$ for every $n \geq 1$.
2. A sequence is decreasing if $a_n$ > $a_{n+1}$ for every $n \geq 1$.
3. If a sequence is increasing or decreasing, then we call it monotonic.
4. A sequence is bounded above if there exists a number N such that $a_n \leq N$ for every $n \geq 1$.
5. A sequence is bounded below if there exists a number M such that $a_n \geq M$ for every $n \geq 1$.
6. A sequence is bounded if it is both bounded above and bounded below.
7. If the sequence is both monotonic and bounded, then it is always convergent.

Overview:

1.
Difference between monotonic and nonmonotonic sequences
Show that the following sequences is monotonic. Is it an increasing or decreasing sequence? 
2.
Difference between bounded, bounded above, and bounded below
Determine whether the sequences are bounded below, bounded above, both, or neither 
3.
Convegence of sequences
Are the following sequences convergent according to theorem 7?
