Animations are always numbered in the order as you apply them. So if you first animate a shape and then add animation to the text placeholder — then that’s going to be the sequence in which they will animate. However, it is possible to re-order your animations as needed. You may want to consider re-ordering of animations so that the sequencing happens as per some aesthetics and logic — also Entrance and Exit animations, if applied need to be the first and last animations for any slide object. PowerPoint’s Re-Order options for animations let you play with this sequencing.
