No odd number of odd numbers can sum to an even number.
The numbers are 11, 13, 15, 17 and 19.
Never. When you dont add the same odd number and even number of times. For example: 5 + 3 (2 odd numbers; and even amount of odd numbers ) = 8 5 + 3 + 7 = 15 an odd amount of odd numbers 5 + 3 + 7 + 9 = 24 another even amount of odd numbers. But never if you use the only same number

1 + 1 + 1 + 1 + 5 + 5 = 14
The sum of all odd numbers, up to the odd number (2n-1) is n^2. So the sum of the first 1000 or 10^3 odd positive numbers is (10^3)^2=10^6 Now divide by 10^3 or 1000 since we have 1000 numbers so we have 10^6/10^3=1000 The mean of the first 1000 positive odd numbers is 1000 If you ask the mean of the odd numbers between, 1 and 1000, that is another problem, since there are 500 of them, the answer would be 500^2/500=500 Think of the mean of the odd numbers between 1 and 10, there are 5 of them and there sum is 25 so the mean is 25/5 or 5 **** in general, the arithmetic mean of the first n odd numbers is n^2/n or n. So that is why the number is 1000.

No odd number of odd numbers can sum to an even number.
It cannot be done. Five odd numbers add up to an odd number and so cannot equal 50.

You cannot. The sum of 5 odd numbers must be odd. 30 is not odd.You cannot. The sum of 5 odd numbers must be odd. 30 is not odd.You cannot. The sum of 5 odd numbers must be odd. 30 is not odd.You cannot. The sum of 5 odd numbers must be odd. 30 is not odd.
you can't because any three odd numbers will equal to an odd number. eg. 1+3+5=9

1, 3, 5, 7.
They are all the 4 digit numbers starting with 1 and ending with 1, 3, 5, 7 or 9. Since there are 500 of them, I will not list them.
