Answer:

Can you find three odd numbers which sum to 30?

No.

Two odd numbers will always sum to an even number. For example, 5 + 7 = 12.

But if you take three odd numbers, they will always sum to an odd number. For example, 5 + 7 + 17 = 29.

So, three odd numbers can never sum to an even number. But 30 is an even number. So no three odd numbers can ever sum to 30
