Maybe I'm missing something -- but I only see two ways of laying these stones to make a 3-foot-wide path. I assume you don't want to cut these stones so you must lay them perpendicular to the sides of the path.
You either lay them in rows of three across -- with the 1-foot long sides parallel with the sides of the path -- or each stone is placed the other way with the 3-foot long sides parallel with the sides of the path.
Hello,
I'm trying to find the following sequence that relates to the number of ways that paving stones can be laid to make a 3-foot-wide path using 3-foot
by 1-foot stones.
This is a very complex problem, and I'd appreciate a little help to start me off in the right direction, or some links to a similar problem. I know Dr. Math has a link, but can someone give me another?
Thank you. Have a good weekend :]

I misstated the previous answer. Sorry.
