**Susan**, Monday, March 5, 2012 at 2:23pm1+4(n-1) where n is the day number

on day 10

1+4(10-1)=37

on day fifty

1+4(50-1)=197

**Steve**, Monday, March 5, 2012 at 3:52pmDay 3 does not fit: 1+4*2 = 9

Since the difference is changing by 4 each day, we will have a quadratic:

Day n: 2n^2 - 2n + 1

**Sandro**, Friday, April 27, 2012 at 5:50pmWhat do you mean by the ^ in your equation Steve? I don't really understand the 2n^2-2n+1. I did figure out it was a quadratic equation, and actually happened to figure out the entire problem until I noticed it said "Write a description or formula that allows me to figure out the number of tiles for any day number?"
