Yes, if you add 22 and 1, for example.
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.
23-13 = 10
The sum of two odd numbers never makes an odd number. Only the sum of an odd number and an even number makes an odd number.
23 is an odd number.
All non-even numbers are odd. All squares of even numbers are even. All squares of odd numbers are odd. Therefore all numbers which are odd and not the square of an odd number are the solution set. It contains: {3, 5, 7, 11, 13, 15, 17, 19, 21, 23, 27, 29, 31, ...}
23 is an odd number.
21, 23 ... (19, both numbers would be odd) Do you know what odd and even means?
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.
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.
6 9 11 23
The odd numbers between 3 and 23 are 3,5,7,9,11,13,15,17,19,21, and 23
