Hmmm.. bingo? Is 15 early teens?

Yeah ig you could say 15 is early teens

It’s exactly mid teens

Not exactly but basically yea

Teens are 10-19
15 is the middle of that

Well if you include 19, then no 15 is not thats 16
It goes 13, 14, 15, 16, 17, 18, 19
16 is the middle

Your definition of teen is just to have teen in the number but the suffix -teen comes from 10

Then its 14 1/2 because we're not including 20
