If by "smaller than ten" you mean closer to zero than 10, then
sum = -9 + -7 + ... + -1 + 1 + ... + 7 + 9 = 0
If you mean the numbers less than 10, then:
sum = 9 + 7 + ... + 1 + -1 + -3 + ... = -∞
If you mean the counting numbers less than 10, then:
sum = 1 + 3 + 5 + 7 + 9 = ½ × 5 × (1 + 9) = ½ × 5 × 10 = 25
All odd numbers are the sum of two consecutive numbers. Odd multiples of 7 less than 25 are 7 and 21.
The sum of two odd numbers is always even.
The two numbers are 15 and 31. 15 + 31 = 46.
The sum of two odd numbers is always even.
The smaller number of the two is 11. The other is 13.
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 an odd number of odd numbers will be odd.
All odd numbers are the sum of two consecutive numbers. Odd multiples of 7 less than 25 are 7 and 21.

The two numbers are 15 and 31. 15 + 31 = 46.
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 two odd numbers is always even.
The smaller number of the two is 11. The other is 13.
