    Logic / Math Puzzle... 1=1 2=1 3=3 4=8 5=55 6=? This is the first puzzle I've devised myself. I hope you don't solve it too fast. :)

      Two shots: a. 144 b. 987 If one of these is right, I'll tell you where they came from! ;P Cheers, Peter [edit] should have refreshed! Didn't see your answer just above. [/edit]

        Both of those are correct. I think you have the solution. What is it?

          a. Prime-indexed terms of the standard Fibonacci sequence b. Knuth's Fibonacci (or circle) product or, (where they came from) sequences A121567 and A101361 from the Online Encyclopedia of Integer Sequences[^] Just type "1,1,3,8,55" into the search box. That URL is a wonderful timewaster (and might even impress those who peek over your shoulder! :-D ) Cheers, Peter

            You have just been awarded more points than I have ever awarded anybody! Sure, they're virtual points, but still. That's crazy that there's a website that actually lists that sequence. You are correct. This is how I would represent the sequence: f(n) = NthFibonacci(NthPrime(n)) Assuming the 1st Fibonacci number is 0 and the first prime is 2.

                They are the 6th and 7th elements of the sequence. Upset you didn't figure it out? ;P

                  No, upset at you for being ambiguous! ;p Thought it was both correct for 6 :(

                    You're cheating ! That's ALWAYS a correct answer. And moreover, it's my cheat, my own, my precious :-D .

                      How about the 'Eban' numbers? 2, 4, 6, 30, 32, 34, 36, 40, 42, 44, 46, ... [EDIT] Or the 'emirps'? 13, 17, 31, 37, 71, 73, 79, 97, 107, 113, ... Get it? Or not?

                        I am now officially addicted to that site. It is a browser narcotic for nerds (sorry if I offended anyone!) -Z a.k.a. 'The Nerdinator' (don't ask...)
