Puzzles and brain teasers have been a favorite way to test intelligence and logical thinking for centuries. They challenge our ability to recognize patterns, think critically, and analyze details that often go unnoticed. Today, we bring you an intriguing IQ test that has left many people puzzled.
Take a look at the number grid in the image above. Your task is to find the missing number in the bottom right box. At first glance, the numbers might seem random, but there is a clear pattern hiding within the grid. Can you find it? Before you scroll down for the solution, take a moment to try solving it yourself!
Common Mistakes When Solving Puzzles Like This
Many people struggle with puzzles like this because they focus on the numbers individually instead of analyzing the relationships between them. Here are some common errors people make when attempting to solve this puzzle:
- Looking for a Simple Numerical Sequence: Some expect an arithmetic or geometric progression, but this puzzle involves more complex relationships.
- Ignoring the Rows and Columns: Many overlook how the numbers interact both horizontally and vertically.
- Missing Hidden Operations: Sometimes, a puzzle requires multiple operations, such as addition and subtraction, which are easy to miss.
- Rushing to a Conclusion: Without taking the time to test different strategies, solvers often make incorrect assumptions.
If you found yourself stuck, don’t worry! Now, let’s break down the solution step by step.
Step-by-Step Guide to Solving the Puzzle
Step 1: Observe the Grid Structure
The grid consists of three rows and four columns. Each number contributes to a hidden calculation that determines the missing number.
| 2 | 8 | 7 | 6 |
|---|---|---|---|
| 9 | 5 | 9 | 5 |
| 9 | 7 | 4 | ? |
Step 2: Identify the Pattern
To find the missing number, let’s examine the relationship between the rows and columns. One key observation is that the sum of the numbers in each row interacts with the sum of certain column elements.
Step 3: Calculate the Total of the Last Row
Looking at the final row:
- The sum of the numbers in the last row (excluding the missing number) is: 9 + 7 + 4 = 20
- This sum needs to be adjusted by subtracting the sum of specific elements in the corresponding columns.

Step 4: Find the Subtraction Factor
By analyzing the previous rows, we notice a pattern involving subtraction:
- The total of the final row is adjusted using the sum of numbers in the second row’s last two columns.
- The relevant numbers are 5 and 6 (from the second and first row’s last columns).
Thus, we perform the operation:
20 – (5 + 6) = 9
Step 5: Verify the Solution
Let’s check if our approach holds across different rows:
- The total sum for previous rows follows a similar calculation.
- Each row is structured in a way that ensures consistency with this method.
Since everything aligns correctly, we can confidently say that the missing number is: 9
