@satellite73  would it be an=33+(n-1)*2
row 17 has 65 chairs?

anonymous · Answer

or @Directrix  is that right, I remember doing this with you.- I believe.

anonymous · Answer

Mind if I give it a crack? The number it increasing by each row is 2 right?

anonymous · Answer

yeah so it would be 33+(17-1)*2

anonymous · Answer

ultimately giving us 17=33+32
17=65 right?

anonymous · Answer

I remember this. I think we were looking for the number of seats in row 19 on that other problem.
