an increase of vs an increase in

Both "an increase of" and "an increase in" are correct, but they are used in different contexts. "An increase of" is typically followed by a specific amount or percentage, while "an increase in" is followed by the thing that is increasing. Therefore, they are not directly comparable as they serve different purposes.
