There are also mathematical equations that require a lot of creative ideas
This problem, which has confused many people on the Internet, has not only one, but also two correct answers, Telegrafi reports.
Most know to find one, which for them is a clear answer, but the team of Go Tumble, who invented this puzzle, says that only one in a thousand participants can provide two correct answers.
So let’s move on: if one of your answers is 40 , then you are absolutely right! So if you add the sum of the first equation to the second task, your answer will be the sum of the second equation.
Here is what this model looks like:
The first equation: 1 + 4 = 5.
The second equation: 2 + 5 (plus the previous sum 5) = 12.
Third equation: 3 + 9 (plus the previous sum 12) = 21.
The fourth equation: 8 + 11 (plus the previous sum 21) = 40.
Once you spot the pattern, finding the answer is not very difficult.
But can you recognize another model between these equations and find another answer? It’s quite tricky, so you’ll have to think outside the box.
