1, 3, 5, 7, 9, 11 and so on.
None. All counting numbers are even or odd.
When the difference between two counting numbers is odd, it implies that one number is odd and the other is even. This is because the difference between an odd and an even number is always odd. As a result, the sum of the two numbers will be odd as well, since adding an odd number to an even number results in an odd sum.
1, 3, 5, 7, 9 counting by twos to 99 are the odd numbers. 2, 4, 6, 8, 10 counting by twos to 100 are the even numbers.
Any product of two or more odd numbers that are larger than 1. For example, 33 = 3*11 is odd and composite.
All numbers are either odd or even, none are both, so less than 30 there are 29 counting numbers that are either odd or even but not both. (Assuming you mean starting to count with 1.)
The sum of the first 500 odd counting numbers is 250,000.
No.
None of them. All counting numbers are either odd or even.
