16+25 = 41 which is an odd number and also a Prime number

25 is an odd number
33 + 25 + 16 = 74
To divide 50 into 5 odd numbers, you can start by finding the middle number, which is 25. Then, you can subtract consecutive odd numbers from 25 to get the other numbers. For example, 25 - 4 = 21, 25 - 2 = 23, 25 + 2 = 27, and 25 + 4 = 29. These five numbers, 21, 23, 25, 27, and 29, are odd and add up to 50.
Lets find out.2 + 3 = 5 (Odd)4 + 7 = 11 (Odd)12 + 13 = 25 (Odd)So it appears that the sum of an even and odd number is an odd number.

Oh, what a happy little question! Let's take a look at those prime numbers. When we add them up, we find that their sum is actually even. Isn't that just a delightful surprise? Remember, in the world of numbers, there's always a little bit of magic waiting to be discovered.
The sum of the even numbers is (26 + 28 + ... + 100); The sum of the odd numbers is (25 + 27 + ... + 99) Their difference is: (26 + 28 + ... + 100) - (25 + 27 + ... + 99) = (26 - 25) + (28 - 27) + ... + (100 - 99) = 1 + 1 + ... + 1 There are (100 - 26) ÷ 2 + 1 = 38 terms above which are all 1; their sum is 38 x 1 = 38. So the difference of the sum of all even numbers and all odd numbers 25-100 is 38.
The number 25 is odd because 25 will not be divisible by 2.
No two odd numbers can sum to 7.
