Because every number is either odd or even.
Even numbers are divisible by two, which means that (with the exception of 2 itself) they by definition are not prime.
No. Odd numbers can be greater than, smaller than, or equal to prime numbers.
All prime numbers other than 2 are odd numbers. 2 is the only even prime number.
That's not true.
An odd number greater than 2, less than 20, and not prime is 9. It fits the criteria as it is odd, falls within the specified range, and is not a prime number since it can be divided by 1, 3, and 9. Another example is 15, which also meets all the conditions.
odd
No. Odd numbers can be greater than, smaller than, or equal to prime numbers.
All prime numbers other than 2 are odd numbers. 2 is the only even prime number.
That's not true.
All prime numbers greater than 2 are odd numbers. The sum of any two odd numbers is always an even number, and no even number greater than 2 is a prime.
No, says the number 9.
odd
An even number because every prime number gretaer than 2 is odd.
3, 5, or 7
No. The first odd number, counting up from one, that is not a prime number, is 9.
The only number that is both prime and odd is the number 2. This is because a prime number is defined as a number greater than 1 that has no positive divisors other than 1 and itself. Since 2 is the only even prime number, all other prime numbers are odd.
