Legally yes, but you have to think about the different stages in life with a 18 and 21 year old. An 18 year old could be just graduating high school or just starting college. A 21 could graduating college or in their last year, they could be living on their own. Paying their own bills, the list goes on and on. The age range is fine, but just keep in mind the stages in life.
