12 numbers -1-3-5-7-9-11-13-15-17-19-21-23
To determine whether the sum of several numbers is even or odd, you can count the number of odd and even numbers in the set. If there are an even number of odd numbers, the sum will be even; if there is an odd number of odd numbers, the sum will be odd. For the numbers 13, 45, 24, and 17, there are three odd numbers (13, 45, and 17) and one even number (24), so the sum is odd.
Count how many of the numbers are odd. If an odd number of them are odd, then their sum is odd. If an even number of them are odd, then their sum is even.
