To find the composite numbers greater than 20 but less than 25, we first list the numbers between 20 and 25: 21, 22, 23, 24. Next, we identify which of these are composite. A composite number has more than two factors. **21**: Factors are 1, 3, 7, 21 (composite). **22**: Factors are 1, 2, 11, 22 (composite). **23**: Factors are 1, 23 (prime). **24**: Factors are 1, 2, 3, 4, 6, 8, 12, 24 (composite). So, the composite numbers are 21, 22, and 24. Thus, there are **3** composite numbers greater than 20 but less than 25.
Not all numbers between 20 and 28 are composite numbers. 23 is a prime number.
