Very confusing
In any three-number formation (eg 1 + 7 = 8), the sum of the three numbers is even. This is because in the possible combinations odd + odd = even, odd + even = odd and even + even = even, the sum of the three numbers in any such combination is always even.
We need three of such combinations, which would need to total an even number.
And yet, 1 + 2 + ... + 9 = 45 which is odd.
So, question is flawed.
