Question

3. Suppose that (x,) is a bounded sequence and let
T = {t€R:t < I, for infinitely many terms r,}.
Prove that there exists a subsequence of (rn) converging to sup(T). Where precisely in your argument
is the assumption of the boundedness of the sequence (r,) used?
4. Suppose that f,g : [0,1] [0, ac] are continuous functions and that

Expert Solution

Given:

Since you have asked multiple questions, we will solve the first question for you. If you want any specific question to be solved, then please specify the question number or post only that question.

$Let (x_{n}) is a bounded sequence . T = \{t \in ℝ : t < x_{n}, for infinitely many terms x_{n}\} Let x_{n_{k}} be the subsequence of (x_{n}) To prove that : x_{n_{k}} \to s u p (T)$
