At first glance it looks like a normal school equation, but it is actually much more complicated. In addition, it turns out that this puzzle has two correct decisions! Check whether you will be able to give at least one correct answer. So, the Website
invites the reader to be patient and to take in hands a pencil and a piece of paper. The decision will either please you or leave you in disbelief. Don't rush to scroll down the page until you find the answer. Well, or until you give up.
Decision No. 1 To the sum of each equation must be added to the sum of the previous. So
1 + 4 = 5
5 + 2 + 5 = 12
12 + 3 + 6 = 21
21 + 8 + 11 = 40
Thus, one of the correct answers 40.
Solution # 2 Another pattern can be observed if we use the formula a + b = a + a(b):
1 + (4×1) = 5
2 + (5×2) = 12
3 + (6×3) = 21
Total: 8 + (8×11) = 96
Most people give the second answer. And what happened to you?
