0 TheChad08 Posted August 4, 2012 Report Share Posted August 4, 2012 Find the missing number in this series: 31, 12, 43, 55, 98, ........., 332 Huh? Maybe I've oversimplified it, but I didn't get 441. 31 + 12 = 43 12 + 43 = 55 43 + 55 = 98 55 + 98 = 153 I'd use 153 as my next answer, but it doesn't follow the pattern to reach 332. Can you explain the series? Quote Link to comment Share on other sites More sharing options...

Can you explain the series? part of the fibonacci sequence with the digits reversed: 1,1,2,3,5,8,13,21,34,55,89,144,233,.... becomes 1,1,2,3,5,8,31,12,43,55,98,441,332,...

That explains why it worked perfectly until you hit triple digits. Quote Link to comment Share on other sites More sharing options...
