7 + 9 = 16
All odd numbers are the sum of two consecutive numbers. Odd multiples of 7 less than 25 are 7 and 21.

The sum of the 25 primes less than 100 is even (it is 1060).The first prime number is 2. Every other prime number is odd.So, of the 25 primes less than 100, one is even and 24 are odd.Any two odd numbers sum to an even number. Therefore, an even number of odd numbers has an even sum. So the sum of 24 odd numbers is even.Therefore, the sum of the 25 primes less than 100 is even.

i am a sum. my addends are five different whole numbers. all my addends are greater than zero and less than eleven. all my addends are odd numbers. what am i?
The sum of the five odd numbers between 10 and 20 is: sum = 5 x (11 + 19) / 2 = 75.
If this question means "in the interval 0 to 16 inclusive, is the sum of the odd numbers the same as the sum of the even numbers ?" then the answer is no. The sum of the even numbers is eight more than the sum of the odd ones.
The sum of two odd numbers is always even; the sum of three odd numbers is always odd; the sum of four odd numbers is always even; the sum of five odd numbers is always odd; etc
The sum of the first positive odd integers less than 101 is 10,000.
Considering only the positive ones, 100 is. If you include the negative ones, their sum is infinite.
