23, 25, 27, 29... add two forever.If you want a more mathematical notation, the nth odd number after 21 is2n + 21I don't know how else to say it, because there are infinite odd numbers above 21.
The difference is 2. (23 - 21 = 2).If we are talking about two odd numbers that come right after the number 20 then we mean the two consecutive odd numbers after 20.The difference between any consecutive odd numbers (or between any consecutive even numbers) is always 2.

Let's call the first odd number x. Since the numbers are consecutive, the second odd number would be x + 2. The sum of the two numbers is 44, so the equation would be x + (x + 2) = 44. Solving this equation yields x = 21, which means the two consecutive odd numbers are 21 and 23.
23 is odd. A sum of two even numbers never makes an odd number. Likewise, no sum of two odd numbers makes an odd number. 23 can only be made by adding an odd and an even number.

Yes, if you add 22 and 1, for example.

No, it cannot be done. As 23 is odd, two numbers used would have to be one odd and one even. As 2 is the only even prime number and 21 + 2 equals 23, but 21 is not a prime number, it cannot be done.
They are both odd numbers.
