Hello,

I want to represent users in their teens, 20s, and 30s.

then, the 100 users (in or from) their teens to thirties who have used the application are selected for the study.

Which one is better in formal writing?

Thank you.

    It isn't an obvious age range to choose, so I would be inclined to say "aged between 13 and 39". Using two adjacent age ranges is fine (teens and twenties, fifties and sixties), but it becomes harder to read if you omit one or more ranges in the middle. You could of course use "in their teens, twenties and thirties", which would not be an unusual way of writing it.

    Oh thank you for the reply.
