The sum of any four odd numbers will never be equal to an odd number.
There is no set of four consecutive numbers (odd or even) whose sum equals 169.
All of those numbers are odd, except the 4. If you were referring to the number as a whole, it is odd because the last digit in the ones place is odd.
121 123 125 127
Well, honey, all you need to do is check the last digit of each number. If there's an odd number of odd digits, the sum is odd. If there's an even number of odd digits, the sum is even. So, in this case, 13 and 17 are odd, and 45 and 24 are even, which means the sum is odd without adding them all up. Easy peasy, lemon squeezy!
No 5 odd numbers add up to 100. The sum of any two odd numbers is even. The sum of any two even numbers is even. So the sum of any 4 odd numbers must be even. Take that and add an odd number and the sum must be odd. Therefore, the sum of any 5 odd numbers must be odd. 100 is even. In conclusion: The sum of any odd number of odd numbers is odd.

The sum of any four odd numbers will never be equal to an odd number.
The sum of any four odd numbers will never be equal to an odd number.
The sum of any four odd numbers will never be equal to an odd number.
9801 * The sum of the first two odd numbers (1+3) is 4, or 22 * The sum of the first three odd numbers (1+3+5) is 9, or 32 * The sum of the first four odd numbers (1+3+5+7) is 16, or 42 * ...and so on So the sum of the first 99 odd numbers, using the pattern above, would be 992 or 9801.

The numbers are 57, 59, 61 and 63.
Yes, that is true.
There is no set of four consecutive numbers (odd or even) whose sum equals 169.
The numbers are 57, 59, 61 and 63.
The answer will be even because if the numbers are even, the answer will be even.
