The natural numbers between 15 and 30 are simply all of the integers from 16 to 29.
33, 35, 39, 45, 49
for (int i = 15; i < 30; i += 2) cout << i << endl;
There are 7 odd numbers between 16 and 30. To find this, you can subtract the largest odd number less than 30 (29) from the smallest odd number greater than 16 (17), then divide by 2 and add 1. So, (29-17)/2 + 1 = 7 odd numbers between 16 and 30.
The sum of all the odd numbers between 1 and 30 (2-28) is 784. If you include 30 the result is 900.
The odd numbers between 30 and 40 are: 31 33 35 37 39

I was able to get the number 30 by adding 4 odd numbers 3 + 7 + 5 + 15 = 30 But i can't add 5 odd numbers to get 30

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]
