WebTheorem 2.4: Every convergent sequence is a bounded sequence, that is the set fx n: n2Ngis bounded. Proof : Suppose a sequence (x n) converges to x. Then, for = 1, there exist Nsuch that jx n xj 1 for all n N: This implies jx nj jxj+ 1 for all n N. If we let M= maxfjx 1j;jx 2j;:::;jx N 1jg; then jx nj M+ jxj+ 1 for all n. Hence (x n) is a ... WebDefinition2.1Monotonic sequence. A sequence sn s n of real numbers is called monotonic if one of the following is true: For all n ∈ N, n ∈ N, we have sn ≤sn+1. s n ≤ s n + 1. For all n ∈ …

Theorem 6.19. Bounded Monotonic Sequence. If a sequence is bounded and monotonic then it converges. We will not prove this, but the proof appears in many calculus books. It is not hard to believe: suppose ...
