How about a math problem? It is said that engineers take 3 minutes to resolve this, architects 3 hours, and doctors 6 hours. What is the 6th number?
1, 2, 6, 42, 1806, ______?
It took me about 3 minutes to figure this out so I guess the "engineers take 3 minutes" line applies (even though I haven't been an engineer since undergrad, lol).
