BaalChatzaf Posted March 21, 2015 Share Posted March 21, 2015 1,11,21,1211,111221,.....what are the next five items? Great praise goes to the one who can find the next five items,greater praise goes to the one who can articulate the rule by which the sequence is generated.Ba'al Chatzaf Link to comment Share on other sites More sharing options...
william.scherk Posted March 21, 2015 Share Posted March 21, 2015 1,11,21,1211,111221,.....what are the next five items? Tricky. I wonder if these are not numerals only, but also descriptors. How about 312211, then 13112221, then 1113213211?The first line is described by the second line: one 1, and so on: two ones; one 2, one 1 ...

Gary Fisher Posted March 22, 2015 Share Posted March 22, 2015 That's wrong. The sequence should be: 1 11 21 1211 111221 102211 11102221 1011010211 11010211011101221 2110111012211010110112211 Guess the next one. Link to comment Share on other sites More sharing options...

That is why we do not permit zeros. We describe only what is there, not what is not there. Link to comment Share on other sites More sharing options...
