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 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
Yes, if you add 22 and 1, for example.
21, 23, 25, and 27
17, 19, 21 and 23.
Three prime numbers whose sum is 42 are 23, 17 and 2
15, 17, 19, 21 and 23.
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.
9 & 23
-397
They are both odd numbers.
