So I recently received an e-mail from a friend, a brain teaser of sorts. It's not one of those "90 percent of people give blah blah answer, only 10 percent say blah blah" (though it did have some statistic thing...but whatever).

Anyway, it's a number puzzle, which you really have to let go of math and see patterns for. I enjoyed it, so here it is:

"First you have to have Excel on your computer. If not just delete this email. The missing number is the password to open the Excel Spreadsheet attached to this email. If you can open the spreadsheet add your name, save it and attach to a new email and send it on.

It is said that engineers take 2 minutes to resolve this, architects 3 hours, doctors 6 hours and Supervisors/Managers 10 hours.

If you guess which the 6th number is, you'll be able to open the excel file. Once you discover it, enter your name, save it and send it on.

What is the 6th number in the below series?

1, 2, 6, 42, 1806, ___???

Good luck!

Here's a link to the Excel file. Have fun, while I finish today's Diabolical sudoku puzzle on Kim's Centro.



  1. Got it. I love a good math puzzle! Took me about 5 minutes to realize what was going on.

  2. Ok, so what is going on?
