0 Guest Posted June 21, 2007 Report Share Posted June 21, 2007 It's secret is to say whay you see on each line and what you see becomes the next line. For full answer see below. Line 1 is "Two ones" (2 1) Line 2 then becomes "One two, and one one" (1 2 1 1) Line 3 therefore is "One one, one two and two ones" (1 1 1 2 2 1) Line 4 is "Three ones, two twos and one one" (3 1 2 2 1 1) Line 5 is "One three, one one, two twos and two ones" (1 3 1 1 2 2 1 1) Quote Link to comment Share on other sites More sharing options...

0 Guest Posted February 4, 2008 Report Share Posted February 4, 2008 I thought of a puzzle based on this topic, so I'm posting it here. What is the next number in this sequence? 421 2 488 504 421 ? Trying to figure this out away from the computer will probably not help you. The sequence is not defined mathematically. The sequence is finite, and it is within your power to change later numbers in the sequence, although not the next one. The first sentence my original posting is a clue.

0 Guest Posted February 6, 2008 Report Share Posted February 6, 2008 Is it 1 3 1 1 2 2 1 1? The same as the other one? I did this without any thinking, just using the clues.

Although i believe those were there just to confuse us right? No to all three questions. The pattern in the sequence that I posted would be very hard to figure out without looking at any of the clues that I posted. I may post more clues later.

0 Guest Posted February 6, 2008 Report Share Posted February 6, 2008 My next clue is to expand the original riddle by giving you more of the sequence. Reread the other clues if you like, it may help you. The following is a sequence that is based on this topic. What is the next number in this sequence? 421 2 488 504 421 113 421 113 3933 3375 4154 4000 1216 4000 4000 4219 4000 4219 4000 ? Sorry if this is a stupid sequence and the answer ends up making you groan, but I thought of it so I figured I'd give it a try. Quote Link to comment Share on other sites More sharing options...
0 Guest Posted February 9, 2008 Report Share Posted February 9, 2008 there is a slight alternative 1 1 2 1 1 2 1 1 3 1 1 2 .... go figure I have not seen this version before and it intrigued me. (Actually I think there is a minor error in the second line: 1211 should be 1112) I have studied the other version and it goes on indefinitely and the largest digit is a three (3). However, this version, when continued, differs in two significant ways: 1. It is finite (i.e. it starts to repeat) 2. The largest digit is a four (4) Here's the whole sequence: 1 11 21 1112 3112 211213 312213 212223 114213 31121314 41122314 31221324 21322314 21322314 The generic pattern is: a1b2c3d4, where a, b, c, d are the total number of occurrences of the digits 1, 2, 3, and 4 in the previous line. Thanks for this new way of looking at an old problem! Quote Link to comment Share on other sites More sharing options...

0 Guest Posted April 26, 2008 Report Share Posted April 26, 2008 The below is a number puzzle. It should be read left to right, top to bottom. Question 1 What is the next two rows of numbers. Question 2 How was this reached. 1 1 2 1 1 2 1 1 1 1 1 2 2 1 ? ? ? ? ? ? An alternate solution: Given that the first three are starting conditions, then the fourth line could be: 21111211 Explanation: * The last two digits alternate between 11 and 21 * The first two digits, in the first three sequences repeat * Interior numbers are shifted right Hence the next number would be: 1221111221 Ta da!

0 Guest Posted May 25, 2008 Report Share Posted May 25, 2008 (edited) Ano, I love this problem! "The below is a number puzzle. It should be read left to right, top to bottom. Question 1 What is the next two rows of numbers. Question 2 How was this reached. 1 1 2 1 1 2 1 1 1 1 1 2 2 1 ? ? ? ? ? ? " 3 1 2 2 1 1 Ano, now to explain... Ano, first, seperate the number sequence into groups of numbers based on what number they are, for example '1 1 1' '2 2' and '1'. Then, take the total number of numbers in the first group -there's 3 ones, so we use 3- and then put what number was counted -in this group, 1-, and repeat with the remaining numbers. Ano, the next line would be '1 3 1 1 2 2 2 1', following the same process as above... Ano, this is a rather old puzzle, and I've seen it several times in books, school newspapers, and on the internet....
