The next episode
The next episode of "Scorpion" (titled "This Is The Pits") will not air until December 12th...which is a couple of weeks from now. Lea Thompson will also reprise her role in this episode as Paige's mother Veronica as well.
This best explains why there was no preview for the next episode during the end credits sequence.
