Sequence Puzzle for 1 June 2015

June 1st, 2015 by Math Tricks | 5 Comments | Filed in Math Patterns



Hello, hello!

Today’s sequence puzzle made the NY times back in the 1990’s.  Take a careful look and see if you can come up with the next number in the sequence:

2, 3, 3, 5, 10, 13, 39, 43, 172 . . .

So, what is the next number, and what is the formula?
