odd
All prime numbers other than 2 are odd numbers. 2 is the only even prime number.
The first number is odd, the second is odd. Odd + Odd = Even ie the sum is even. Either number is greater than 2 so their sum is greater than 2. All even numbers greater than 2 are composite.
There is no such pattern because there are no even odd numbers. Odd numbers, by definition, are odd and therefore, not even.
The answer depends on how many odd numbers are being added together: even numbers make no difference.If the count of odd numbers is odd then the total is odd, andff the count of odd numbers is even then the total is even.

Multiply two odd numbers Add an even and an odd Subtract an odd and an even
21, 23 ... (19, both numbers would be odd) Do you know what odd and even means?
Always. even + even = even odd + odd = even even + odd = odd odd + even = odd To summarise, if you add like numbers you get even, otherwise you get odd.
All the other prime numbers are odd. Every other pair of odd numbers has at least one even number between them. Even numbers greater than two are not prime.
The sum of two odd numbers is always even; the sum of three odd numbers is always odd; the sum of four odd numbers is always even; the sum of five odd numbers is always odd; etc
The product of two odd numbers is always odd.
