Here’s a quick but hard brain teaser to challenge your ability to find a pattern. In the table below, each row across follows the same pattern. See if you can discern the pattern and fill in the missing number in the bottom row.
For added challenge, time how long it takes you to complete the puzzle. Then, pass it along to someone else and see who can solve it faster…
Have you solved it yet? If not, here’s a hint:
If you read your figures like words in the West,
then multiply your efforts and subtract the rest.
WARNING: Answer and solution follows. Try to solve the puzzle before you read further.
(7x4)-8 = 20
(3x9)-7 = 20
(3x8)-4 = 20
The answer is 3.
