If you are a student asking this question, then I suggest that you work on it yourself for a while, and then post both your complete question and your proposed answer.
This is a classic question in SQL, and there are many answers, all of which teach a lot of how SQL works.
Some questions you should consider:
What do you do if the table has less than 3 rows?
What do you do if two values are tied (include them, so more than 3 rows are returned? Return only 3, so that one or more rows get excluded arbitrarily? Return an error message, saying there is a tie?)
