4-6-9-13??

My first year at my current school, I started with 4 students...yes, I quickly escalated to 6 and ended the year with 8...but originally, I got to settle in with 4. That was nice.

This year, I started with 6 (it was supposed to be 8, but two moved before school started). I am ending with 8 again.

Next year, I am projected to start with 9.

So, it was plus 2 for the second year, plus 3 for the third...if this pattern continues, will I start with 13 next year??

(See, i can do math when I need to!)
