The answer depends on how many odd numbers are being added together: even numbers make no difference.If the count of odd numbers is odd then the total is odd, andff the count of odd numbers is even then the total is even.
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.

Yes, all you have to do is to count the number of ODD numbers in the list. If it is odd, then the sum will be odd; if even, so will the sum. Knowing this can help you run a quick validity check when you sum up a list of numbers. (The method works because: a) the sum of two even numbers is even, and b) the sum pf two odd numbers is even, but c) the sum of an even number and an odd number is odd. Hence, if you only determine whether there are any unpaired odd numbers, you know the answer.)
Count the number of negative numbers. If this is an even number, the sign is + and if it is odd, the sign is -.

Go through each of the numbers, and count how many of them are odd. If you count an odd number of them, then their sum is odd. If you count an even number of them, then their sum is even.
No one can count because numbers go on forever.
999 What is even odd? 3 digit odd numbers 101,103,105...999 so count them = 450 3 digit even numbers 100,102,104...998 so count them = 450
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.

To find the four odd numbers just before 200,003, you can start from 200,003 and count backward, keeping only the odd numbers: 200,003 (Odd) 200,001 (Odd) 199,999 (Odd) 199,997 (Odd) So, the four odd numbers just before 200,003 are 200,001, 199,999, and 199,997. visit wrostgame .com
There are 52/2=26 even numbers in 52. Hence there are 26 odd numbers in 52, since 1 the first number is odd. You also get 26 if you count them: 1,3,5, ... 51.
25 if you count 1, 24 if you don't.
Odd integers are whole numbers that are not evenly divisible by 2. If you count, starting at 1, you will have alternating odd and even numbers. 1 is odd, 2 is even, 3 is odd, 4 is even, 5 is odd, 6 is even, 7 is odd, and so forth to infinity. Negative numbers have the same property (minus one is also odd, etc.) and zero is also an even number.
