The sum of 3 odd numbers is odd while 30 is an even number. So there is not a valid answer in the normal sense.
However, in base 9,
5 + 6 + 17 = 30
[In base 10, the above is 5 + 6 + 16 = 27]
There are 44 odd numbers between the two.
15
No, because two odd numbers always add together to be an even number, and a even plus an odd number is an odd number, example: 3+1+11=An even number? 3+1=4 4+11=15 Is 15 even? No. 3+1+11= An odd number (15)
They are the numbers that when divided by 2 leave a remainder of 1
You cannot add 4 odd NUMBERS to make an odd number, so you have to think constructively...eg 1 + 3 + 15 = 19. There are other similar solutions...
There are 44 odd numbers between the two.
You can add any one of 13, 15, 17, 19 and 21.
Impossible.

The numbers are 11, 13 and 15.

16
The numbers between 10 and 20 that are not prime are 12, 14, 15, 16 and 18. So 15 is the odd number and the rest are even numbers.
13, 15, 17 and 19
