I like to run.  The first day I ran 1 mile.  The second day I ran 3 miles.  The third day I decided to cut back and ran only 2 miles.  The fourth day I ran 4 miles.  The fifth day I decided to cut back again and ran only 3 miles.  The sixth day I ran 5 miles and the seventh day I only ran 4 miles.  If my pattern continues, how long will it take me to run over 50 miles?
