Let $\mathbb{R}$ be the D1817: Topological ordered set of real numbers such that
(i) | $x, y : \mathbb{N} \to \mathbb{R}$ are each a D336: Convergent sequence in $\mathbb{R}$ |
(i) | \begin{equation} \forall \, n \in \mathbb{N} : x_n \leq y_n \end{equation} |
Then
\begin{equation}
\lim_{n \to \infty} x_n \leq \lim_{n \to \infty} y_n
\end{equation}
