If you’re the kind of person who loves testing your logic and stretching your brainpower, this number puzzle is right up your alley. At first glance, it looks simple—just a few circles with numbers. But if you blink, you might miss the pattern that holds the real answer.
The Setup: Simple Numbers, Hidden Complexity

You’re given a 3×4 grid. The first three rows are filled with the numbers 1 through 9, neatly ordered from left to right. The last row is where things get interesting: it contains 27, 38, and a question mark. Your job? Figure out what number replaces that question mark.
This is where most people start guessing blindly or get tricked by misleading patterns. But there’s a clear and logical explanation hiding in plain sight.
The Mistake Most People Make
Most solvers begin by looking at the rows, trying to add, subtract, or multiply horizontally. That’s understandable—many classic puzzles work that way. But here, the key is not in the rows. It’s in the columns.
When you shift your focus from left to right and start looking top to bottom, the answer begins to reveal itself.
Column Logic: Step-by-Step Breakdown
Let’s focus on the first column:
- Top to bottom: 1, 4, 7
- Add them up: 1 + 4 + 7 = 12
- Now notice the number underneath that column: 27
- So, 12 + 15 = 27
Interesting. The total of the column is 12, and when we add 15, we get 27.

Let’s try the second column:
- Top to bottom: 2, 5, 8
- Add them: 2 + 5 + 8 = 15
- The number underneath is 38
- And 15 + 23 = 38
Now look at the pattern between 15 and 23—the added values increased by 8.
Let’s apply the same pattern to the third column:
- Numbers: 3, 6, 9
- Add them: 3 + 6 + 9 = 18
- If we follow the pattern, the next added number is 31 (15 → 23 → 31, increasing by 8)
Final step: 18 + 33 = 51
Boom. There’s your answer.
The Final Answer Is: 51
That’s it. Once you look at the puzzle the right way, it’s not just solvable—it’s elegant.
