數學小考 － 動動腦，來解題

This is a mathematical challenge, and it's been said that :

這是項數學挑戰！有這麼一種說法：

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.

你若是工程師，你應該可在三分鐘內（30秒左右吧）解開這道題；你若是建築師，給你三小時；你若是醫生，給你六小時；你若是會計師，三個月吧～假若你是律師，大概永遠也解不出來。

What is the missing number in this logical series?

問題如下：空格中的數字為？

 1, 2, 6, 42, 1806, _______???

Good luck

祝好運
