Discussion Overview

The discussion revolves around identifying the next line in a numerical pattern puzzle. Participants are exploring the structure of the sequence and the rules governing the placement of numbers in each row.

Discussion Character

  • Exploratory
  • Debate/contested
  • Mathematical reasoning

Main Points Raised

  • One participant finds the puzzle challenging and suggests that it may be too difficult for some.
  • Another participant presents a detailed explanation of the pattern, indicating that each row corresponds to its row number in terms of the count of digits.
  • This explanation includes a method for placing numbers based on their position relative to the previous row, with specific examples provided.
  • A later reply requests clarification of the explanation, indicating that the initial description may not have been clear to all participants.

Areas of Agreement / Disagreement

Participants have not reached a consensus on the clarity of the explanation or the solution to the puzzle, as some are seeking further clarification while others have attempted to outline the rules.

Contextual Notes

The discussion includes assumptions about the rules of the pattern that may not be universally understood, and there are unresolved aspects regarding the clarity of the explanation provided.

I think this one is kind of tough, so if you can't get it after a bit then maybe it's too tough. What's the next line?

1
1 2
1 3 2
3 1 4 2
1 4 2 5 3
1 6 4 2 5 3
3 1 2 6 4 7 5
1 8 2 5 3 7 4 6
3 1 4 2 9 7 5 8 6

1
1 2
1 3 2
3 1 4 2
1 4 2 5 3
1 6 4 2 5 3
3 1 2 6 4 7 5
1 8 2 5 3 7 4 6
3 1 4 2 9 7 5 8 6
6 5 8 1 2 10 3 7 4 9

Now, for the reason why...

As you can see you have multiple rows, and each row number tells you how many digits are in each row. Each sequencial digit from 1 to r (where r is the row number) is in that row. S your pattern (with "0" as a place holder) is like this:

0
0 0
0 0 0
0 0 0 0
0 0 0 0 0
0 0 0 0 0 0
... etc...

So... place the first number in the sequence down:
1
Then, move to the next row since you're reached r.
Next row will give it all away; but see how it works...

Place 1, then 2; but to find out where "2" goes, you need to look at the row before it and start from the left and put it that many places over from the current number you are placing. Take this example.

1 3 2
3 1 4 2

Working on that bottom row you have

1 3 2
0 0 0 0

Place the 1:

1 3 2
1 0 0 0

Now look at the row above. Place the "2" 1 place over since the row above starts with a 1:

1 3 2
1 2 0 0

Now place the "3"... to do that, you'll notice in the row above that 3 comes after the 1, so you need to place the "3" 3 places to the right of the two (and this wraps around). So you then have:

1 3 2
3 1 2 0

Now place the "4" 2 places over from the "3":

1 3 2
3 1 4 2
Clear as mud? I told you it would be hard. Sorry about this one... a little too tough to be seen I guess. No real math, just a dumb pattern that's hard to see.
