It is said that engineers take three minutes to resolve this; architects take three hours and doctors six hours. Salespeople just delete it.
If you can guess the 6th number, you'll be able to open the attached Excel file. Once you discover it, put your name, save it and send it on.
Which is the 6th number? 1, 2, 6, 42, 1806, ___???

 
Makes my brain hurt! Salesperson Here!!
 
Got it! (3263442) Didn't time myself, but I saw the pattern instantly. I'm not good at math, but I'm a weaver, and, therefore, see patterns quickly.
 
dam dam....I got it thanks to the key word "pattern"....and less than a few seconds........ I'm very very very surprised!

Wow! I got it in about 2 minutes! I'm very surprised. It probably took me most of that time to do the multiplication! (not the best at math!)
 
I din't look at the responses, but I think I got it. took me less than a minute using a calculator...
If I'm wrong, oh well, If I'm right, Woo Hoo!!

My answer is 3,263,442
 
heh heh!

I didn't see an excel file either. But I got what Joe did, so I guess I'm right....
 
Indian giver.....
 
Thought I had it a 2 min, but then the prime number just so high, there was a HUGE gap... then got it about 3 min too.

Did anyone else notice the prime number pattern and go down the wrong path at first?
