WebbLet's consider the sequence a n = 1 n. We have 0 < 1 n ≤ 1 for all n. Therefore, the sequence is bounded from above by 1 and bounded from below by 0. We observe how the upper bound is part of the sequence, a 1 = 1 and, therefore, it is the best possible bound. But the lower bound does not belong to the set. This might make us think that it is ... Webb5 mars 2024 · In this video I will show you how to prove a sequence is bounded. The example is with a sequence of integrals.I hope this helps someone.
Proof that Convergent Sequences of Real Numbers are Bounded
WebbFigure 2.4: Sequences bounded above, below and both. Bounds for Monotonic Sequences Each increasing sequence ( a n) is bounded below by a1. Each decreasing sequence ( a n) is bounded above by a1. Exercise 3 Decide whether each of the sequences defined below is bounded above, bounded below, bounded. If it is none of these things then explain why. WebbIn this video we look at a sequence and determine if it is bounded and monotonic.

Webbn) to be bounded above, provided that we allow 1as a limit. Theorem: (s n) is increasing, then it either converges or goes to 1 So there are really just 2 kinds of increasing sequences: Either those that converge or those that blow up to 1. Proof: Case 1: (s n) is bounded above, but then by the Monotone Sequence Theorem, (s n) converges X Case ...
