I'm having problems with a particular number sequence:

175, 94, 188, 124, 376, 327, 1308, ...

I've tried working out the differences and have came up with this but I can't get anywhere from it.

175 94 188 124 376 327 1308
 -81 94 -64 252 -49 981 
  175 -158 316 -301 1030
   -333 474 -617 1331
    807 -1091 1948 
     -1898 3039
        4937

If someone can point me in the right direction of how to go about solving it.

And, do you know this one? $$1,11,21,1211,111221,312211,13112221,...$$ –  Berci Oct 13 '12 at 0:12

@Berci: 1113213211, the point of asking me that was? –  Colin747 Oct 13 '12 at 0:18
    
Sorry, didn't get your problem. Where is it from? –  Berci Oct 13 '12 at 0:25

Colin, did you try what marty suggested? Did you, for example, divide 188 by 94? 376 by 124? 1308 by 327? Also, in the 2nd line of your triangle, look at the 1st, 3rd, and 5th entries --- do they look familiar? –  Gerry Myerson Oct 13 '12 at 11:46
