I went with p(n) = p(n-2)^2 + p(n-1) But I notice that it doesn't work with the start at 1^2 + 2 != 5. <_< So, assuming that the initial terms aren't purely arbitary (note that they often are in these puzzles), it's back to the pen & paper.

0 Pickett Posted February 9, 2009 Report Share Posted February 9, 2009 This one appears to be the last digit of the fibonacci sequence: 1 2 3 5 8 13 21 34 55 89 144, 233, etc... so, the next numbers would be 9, 4, 3... Quote Link to comment Share on other sites More sharing options...
