Some logical tests may seem obvious, but they often conceal a logic that needs to be recognized. With this logical test, the goal is not to perform a traditional calculation, but to observe a pattern among the different lines. Before you begin, take the time to analyze the structure. The aim is not to guess randomly, but to understand the logic.
As Henri Poincaré said:
“Science is built of facts just as a house is built of stones, but a pile of facts is not more a science than a pile of stones is a house.”
In mathematics, this means looking for the structure and the rule behind the examples.
Why This Type of Challenge Is Educational
Logical sequences are not just games: they are an excellent tool for intellectual training. They engage multiple skills:
- recognition of numerical patterns
- logic and analysis of sequences
- ability to identify a hidden rule
- rigor in reasoning
- observation of variations
This type of exercise highlights something important: a problem that seems simple at first glance can require deep thought.

And You?
What result did you get?
Did you find it quickly, or did you have to go back and check each step?
No matter your level, this type of challenge is an excellent way to strengthen your rigor and logic.
Detailed Solution We Found
Method to Follow
To solve this type of challenge, you need to:
-compare each line with the previous one
-identify the gap between the results
-recognize a logical progression
-apply the same rule to the last case
Observing the Rule
Let’s compare each line:
- 5 + 5 = 10 → 11 ( +1 )
- 6 + 6 = 12 → 14 ( +2 )
- 7 + 7 = 14 → 17 ( +3 )
- 8 + 8 = 16 → 20 ( +4 )
We notice that we add an increasing number each time.
So:
- for 9 + 9 = 18
- we add +5
Calculation
18 + 5 = 23
Result
Answer: 23
Conclusion
The rule becomes clear when we compare each step: we are not performing a fixed operation, but a progressive adjustment that increases with each line.
