In our local pub soccer league each team plays each of the others at home and away during the season. Two seasons ago we had a two-figure number of teams. The number increased the next year, and again this year, but this time the increase was one less than the previous season. This season the number of games played will be over three times the number played two seasons ago. Also, this season’s increase in games played actually equals the number played two seasons ago.
How many teams are there now in the league?
