To instruct the slides to automatically transition from one to the next after fifteen seconds, Mateo should use the "Advance Slide" option. This can be accessed under the "Transitions" tab in PowerPoint. By selecting the desired slide transition and specifying the time duration of 15 seconds, the slides will automatically advance without any manual intervention.
