## Observation is the best approach

If you want to overcome this challenge quickly, the key is in observation. Take a moment to scrutinize the number sequences arranged in each square. By doing this, you are likely to spot a logical pattern, a kind of red thread that will guide you to the missing number. It is this clever deduction that will make all the difference.

## The beauty of digital puzzles

Number puzzles are a fantastic playground to sharpen your logical and mathematical skills. They stimulate the mind, sharpen the reflection and bring a certain satisfaction when one manages to solve them. In our puzzle, each square contains crucial clues which, if deciphered correctly, will lead you to the solution. **Be vigilant**because every detail counts.

## A clue to help you find the solution

If the riddle still leaves you perplexed, we offer you a hint: each square is the scene of a multiplication and subtraction operation. Your task is to figure out how these operations relate to the numbers in each square.

**The solution to our riddle is 17**. But don’t stop there, try to find the reasoning behind this result. This is where the real challenge lies.

## The explanation of the solution

**Here is the key to the puzzle:**

In the first square, we have the following operations:** 3×4=12 and 17-5=12**.

For the second square, the operations are: **7×2=14 and 25-11=14**.

And finally, in the third square: **5×2=10 and 17-7=10**.

This diagram reveals that the number to find was indeed 17. So, **did you manage to solve this riddle without cheating** ?
