I'm not a mathematician so this could be wrong but my understanding of a Fibonacci sequence is that you add the two preceding numbers to get the third number so a Fibonacci strip would be:1 row, 1 row, 2 rows, 3 rows, 5 rows, 8 rows, 13 rows
I have also seen them done with two set of the sequence going in opposite directions:13, 1, 8, 1, 5, 2, 3, 3, 2, 5, 1, 8, 1, 13
I'm sure there is a formula to figure out the sequence if you know how many rows you are doing but I don't know what it is. i would have to get out a calculator and start adding. It wouldn't be hard just take a bit of time. The first example has 33 rows and the second one has 66.
-- Thanks for these details; they help alot. Like, your explanation about going in reverse. That's probably what I've seen alot of around, and had no idea how to do that.
