You will have a long search on your hands because 5 odd numbers will never make 30. Any two odd numbers added together will result in an even number. Any two even numbers also result in an even number. An even and an odd number will always rsult in an odd number, so taking 5 separate odd numbers... odd1 + odd2 = even1 odd3 + odd4 = even2 even1 + even2 = even3 so, after taking 4 odd numbers, the answer is always even. Next... even3 + odd5 = odd As the result of the last calculation is always odd, it will never be 30.
Can not be done! An odd number of odd numbers will ALWAYS add up to an odd number.

No three odd numbers can add up to an even number.
There are no such numbers. The sum of any three odd numbers must be odd. 112 is not.

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.
