A good friend of mine sent me an email, challenged me to solve a mathematical problem. She said that if you’re an engineer, you should be able to solve it in (under) three minutes (more like 30 seconds). If you’re an architect, in three hours. If you’re a doctor, in six hours. If you’re an accountant, in three months and if you’re a lawyer, probably never. Well, if you think you are good at maths or logical problems, here is this challenge :
What is the missing number in this logical series :
1, 2, 6, 42, 1806, ____?
I replied her with my answer and my answer was confirmed correct. Hmm! With the disturbing surrounding (hehe), I managed to solve it in less than one minute. How about you? 🙂
