This was sent to me by an Accountant. The original content goes this way:

 math challenge: accountants can solve this in 3 mins, engs 3hrs, drs 3 days, lawyers never: what’s the sixth number? 1,2,6,42,1806,___?

After successfully giving her the right answer in a minute, I tried to modify it.

programmers can solve 
this in 1 min., 
accountants  in 3 mins, 
engineers 3hrs, 
doctors 3 days,
lawyers never:
what’s the sixth number? 
1,2,6,42,1806,___?

Better try it out! Share it to your friends. It will be fun! Just like I did!
