Brain Teasers
Here’s a puzzle to test your ability to find a pattern and test it against more data.
In this table, each row across follows the same pattern of numbers. See if you can discern the pattern and fill in the missing number in the bottom row. For added challenge (or competition), time how long it takes you to complete the puzzle. Then, pass it along to someone else and see if they can solve it faster. The slower one has to cook dinner!
