Theorem xrlimcnp 24917

Description: Relate a limit of a real-valued sequence at infinity to the continuity of the corresponding extended real function at +∞. Since any ⇝_𝑟 limit can be written in the form on the left side of the implication, this shows that real limits are a special case of topological continuity at a point.
