They are all prime numbers except for 15 21 25 and 27 which are composite numbers
The number 21 would be the answer. 19 and 23 only have two factors, 1 and themselves, as they are prime numbers. 25 only has 1, 25 and 5. 21 has 1, 21, 3 and 7 for 4 possible factors.
there are 3 prime numbers in between 21 and 33... they are 23,29, 31.
23 + 2 = 25
The prime numbers among the given list are 23 and 29. A prime number is a natural number greater than 1 that has no positive divisors other than 1 and itself. In this case, 23 and 29 have no divisors other than 1 and the numbers themselves, making them prime. The other numbers in the list have divisors other than 1 and themselves, so they are not prime.
