i'm guessing that may b there is a sequence each number in the line.
Is the first number 8?
1 7 3 2 5 5 1
1 9 8 6 4 2 2
2 3 1 8 8 4 2
4 9 2 8 7 3 4
8 _ _ _ _ _ _

3rd column, like 1st is "add and take last digit"?

I think I got it.
First column you are adding the sequence 0, 1, 2, 3 (adding 1 each time)
Second column you are adding the sequence 2, 4, 6 (adding 2 each time)
3rd: 5, 13, 21 (adding 8 each time).
4th: 4, 12, 20 (adding 8 each time).
5th: 9, 14, 19 (adding 5 each time).
6th: 7, 12, 19 (unique, adds 5, then adds 7 then adds 9?)
7th: 1, 10, 22 (adds 9, then adds 12, then adds 15?)
Everytime you get a two digit number though, the tens digit is cut off.
So the next line would be 7716111.
EDIT: Think my theory goes along the same lines as orfeo's, hence the same digits for the 1st to 5th columns. 6th and 7th columns seem odd though. Could not spot a relationship between each of the columns.

Originally posted by lauseyI wouldn't be surprised if both of us are seeing the 'effect' of a rule that has more logic to it than that. Your reasoning is essentially similar to mine, though. Some of them I turned into subtraction rather than addition to keep the numbers a bit smaller, but +8 and -2 will amount to the same thing.

6th row seemed to me to alternate: +, -, +, -
We shall just have to wait and see!

Originally posted by fetofsIt seems like it should be something simpler. Originally, we were only given the first 3 rows, which wouldn't be enough info to find an alternating series. Unless theres a connection between columns.
The 6th line seems to me logical on this lines: Add 7, Subtract 8, Add 9...
So there's no change on the last number, 3.
How about 4 for the 7th? There are many sequences possible...

Slippery, if you are there, not suggesting that you give the answer, but are we on the correct path? Maybe even give the next line.
Is there a relationship between the columns?
