The answer is Slide transition
PowerPoint’s slide transition provides a visual effect when you move from one slide to the next. Transitions are used to add smoothness and visual interests to a presentation. To apply the transitions effect, Ryan will be required to select each slide individually and click the transition tab. In the transition to the slidegroup, he should be able to click the more- arrow button to open the transition’s gallery and from there, he will click a transition of his choice and it will be applied.
He can go ahead and click the Effect options and select a time duration to set how fast the transition goes.
