>>13975350I feel like it has 3 different answers
0 because it would be 9, 9 18, 18 which seems like a possible solution.
18 because it would be Fibonacci but with 9 (9, 9, 18, 36)
But it could also be 7 because each of the outer walls/ rows of the triangle each add up to 25
So it would make sense for the bottom row to add up to 25 as well.
But 7 isn’t even listed.
So overall, you can tell the puzzle is sloppily made.
