monotonic sequence theorem

The main goal of this section is to prove that any bounded monotone sequence must converge. So, we start from the definition. Definition 4.1. A sequence (an)n?1
A sequence is said to be monotone if it is either increasing or decreasing. Example. The sequence Common strategies to prove boundedness (for reference).
There may be an overall formula for the terms of the sequence, or a “rule” for getting from one to the However, if a sequence is bounded and monotonic, it is convergent. This is State, prove and apply the Monotone Convergence Theorem;.Proposition 1.4 The sequence an = (1 +. 1. 2n )2n has a limit. Proof. By Theorem 1.3, it suffices to prove {an} is increasing and bounded above. To show it is

Lecture 2 : Convergence of a Sequence, Monotone sequences In the sequel, we will consider only sequences of real numbers. Let us give This proves that yn > x0. D Theorem 2.5: Suppose (xn) is a bounded and increasing sequence.

Not all bounded sequences, like (?1)n, converge, but if we knew the bounded One uses induction to show that (xn) is increasing: xn ? xn+1 for all n ? N.
Figure 2.3: Which sequences are monotonic? Be Dotty Figure 2.4: Sequences bounded above, below and both. Exercise 7 Think of examples to show that:.

If a sequence is monotone and bounded, then it converges. Proof. We consider two cases. Prove the Monotone Convergence Theorem (??) for decreasing
