Q. Is it incorrect to use “and then” when stating the multiple actions of an individual? E.g., “She glanced around the room and then exited for the last time.” If it’s better to omit the and, does that mean there should be a comma in place of the and? How about in this sentence: “He got a DUI then resisted arrest”? Should there be a comma before then?
A. No, yes, and yes. It’s fine to write “and then” as you did in your first sentence. If you leave out and, add a comma before then: “He got a DUI, then resisted arrest.”
