Showing a sub-sequence ($r_{n_{k}}$) converges to $x$ There exists a bijection that $f : N → Q, x \in R$ *$r_{n}$:=$f(n)$ I am asked to show that there exists a sub-sequence ($r_{n_{k}}$) of ($r_{n}$) so that the l...
Let $n_1 < n_2 < n_3$ ,then the limit of $i$ will converges to x. By the density of $Q$ , there will be a $n_1$ that $x−1$ < $n_1$ < $x+1$ Therefore, $x− 1$ < $r_n$ < $x+ 1$ Notices that there exists infinitely many rational numbers belong to the interval and hence, it is always possible.

Does every convergent sequence have a sub-sequence whose terms comes closer than any positive sequence? Let $(x_n)$ be convergent sequence of real numbers and $(y_n)$ be any sequence of positive real numbers , then is...
By definition of convergence (actually, by using the fact that any convergent sequence is a cauchy sequence), $\forall \epsilon > 0, \exists N\in \mathbb{N}: \forall n, m > N, |x_n - x_m| N_1, |x_n - x_m| N_2, N_2 \geq N_1, |x_n - x_m| < y_2$$ You'll get your subsequence $(x_{r_n})$ in question.

Existence of a sub-sequence of non-converge sequence that $|x_{p_n}-L|>\epsilon$ > Let $\\{x_n\\}$ be a sequence that does not converge and let L be a real number. Prove that there exist $\epsilon >0$ and a sub-sequen...
Since $(x_n)$ does not converge to $L$ there is $\epsilon >0$ such that $|x_n-L|> \epsilon$ for infinitely many n. Now, its your turn.

Does every bounded sequence have a Cauchy sub-sequence? In an answer to an earlier question it was explained why a bounded sequence is not guaranteed to be a Cauchy sequence. But does every bounded sequence have a Ca...
No, it is not true in general that every bounded sequence has a Cauchy subsequence. Define a metric $d$ on $\Bbb R$ by $d(x,y)=\min\\{|x-y|,1\\}$, and consider the sequence $\sigma=\langle n:n\in\Bbb N\rangle$. Clearly $d(m,n)=1$ whenever $m,n\in\Bbb N$ and $m\ne n$, so $\sigma$ has no Cauchy subseq...
