There are the infinitely many negative odd numbers and then there are 1, 3, 5, 7, 9, 11, 13 and 15.
15 and 13
no two numbers make 17 odd. It is simply odd by not being divisible by 2. (or by being 1 in mod(2)).

i only know this odd number its 17, 15.
Just add the end numbers, so 3 + 5 + 4 + 7 = 19 which is odd. Alternatively, ignore even numbers [such as 4], and two odd numbers [3 and 5] added always make an even number [8], which leaves and odd number [7] so the answer will be odd. Example; five hundred different numbers, where 483 are even and 17 are odd, then no matter what the actual 500 numbers are the answer will be odd, as there is an odd [17] quantity of odd numbers.
The numbers are 15, 17, and 19.

There are 17 odd numbers between 42 and 76. (76 − 42) ÷ 2 = 17

The numbers are 15, 17, and 19.
They are the numbers divisible by 2 with a remainder of 1
Count how many of the numbers are odd. If an odd number of them are odd, then their sum is odd. If an even number of them are odd, then their sum is even.
