Let's try 99 and 98! 99 is 3 x 3 x 11 and 98 is 2 x 7 x 7 98 and 99 are consecutive numbers, composite numbers, less than 100 and there is no prime numbers between them!
The set of composite numbers includes all whole numbers greater than 1 that are not prime numbers. The first few composite numbers are 2, 4, 6, 8, 11, 13, etc.
11 is a prime number. Multiples of 11 greater than 11 are composite. Composite multiples of 11 in that range are 22, 33, 44, 55, 66 and just keep adding 11 till you get to 396.
2 is the smallest prime number. 9 is the greatest composite number less than 10. The sum of 2 and 9 is 11.
None of the numbers 7, 11, and 13 are composite numbers; they are all primes.
All the multiples of 11 up to 100 except 11 itself which is a prime number

All numbers other than 11, 13 ,17, 19 ,23,29, 31 are composite numbers. eg 10,12,14,15, are composite numbers.
The set of composite numbers includes all whole numbers greater than 1 that are not prime numbers. The first few composite numbers are 2, 4, 6, 8, 11, 13, etc.
22 is a composite number because it has more factors than 1 and itself. The factors of 22 are 1, 2, 11, and 22. All even numbers greater than 2 are composite numbers.
99 is the largest composite number less than 100: its prime factorisation is 3 x 3 x 11
The composite numbers between 11 and 29 are 12,14,15,16,18,20,21,22,24,25,26,27 & 28.
11 is a prime number. Multiples of 11 greater than 11 are composite. Composite multiples of 11 in that range are 22, 33, 44, 55, 66 and just keep adding 11 till you get to 396.
2 is the smallest prime number. 9 is the greatest composite number less than 10. The sum of 2 and 9 is 11.
None of the numbers 7, 11, and 13 are composite numbers; they are all primes.
11 is a prime and contains no composite numbers.
11 and 13 are prime numbers but 15 is a composite number because it has more than two factors
