#### The first solution is:

- Most agree that 1 + 4 = 5.
- In the next line, add 2 + 5 to the sum of 5 in the equation above. That gives you the answer of 12.
- Next, apply the same formula: 3 + 6 = 9, then add the 9 to the sum in the equation above (12) to get the total of 21.
- The last step is to take the 8 + 11 in the last equation, which equals 19, and add it to the sum of the previous problem (21). This gives you a total of 40.

#### However, there is a popular second solution:

- The obvious truth is: 1 + 4 = 5. But you could also reach 5 by adding 1 to 4 times 1.
- In the same fashion, with the second line, 2 + 2(5) = 12.
- And the next line: 3 + 3(6) = 21.
- Using this method to solve the problem, add 8 to 8 times 11 to get 96.

Which solution did you find? 40, or 96?

Or maybe you see the problem in a way different than the two mentioned above? What do you see? What is your interpretation?

Let’s see now 3 time 6 equal 18 then add 3. I think this equals 21.

I say the first solution. Anything else you’re reading things into something which could be plausible, but now you’re getting away from seeing things at face value. I would say folks who are cynics or suspicious of everything will see the second solution. The adult logic pattern does lend itself to the latter, as we have a habit of overthinking things.

I first came up with 52.

1 + 4(1) = 4

2 + 5(2) = 12

3 + 6(3) = 21

8 + 11(4) = 52

the multiplier increases by 1 for every line.
