34 32 36 46 64 75 50 35 34
16 18 14 22 ?? 40 35 15 20 12
?? is a 2-digit number. What is it?
The answer is NOT the one that first crosses your mind. Can you work it out? Give it a go in the forum!
24-The sum of the bottom 2 numbers = te top number in each triangle—
31– Take top number, subtract 2, divide by 2.
24. The difference in each column is the bottom number of the next column, as ‘honore’ said. i.e. first column 34-16=18, 18 is the bottom number of the next column. So, 46-22=24.
The only flaw in this theory, is that the last number on the bottom row should be 14 not 12…
Answer is: 22
24 is the correct answer
