Im pretty sure its 18 unless im reading it wrong
A. The hexagon as the series is adding a side each time. So you started with 3, 4, 5...
-12 n - 24 = -12 (n+2)
-12 (n+2) is the answer
To solve this, you would divide 478 by 18, which equals 26.5555556. Since you can't have half a package of paper, the answer would be 26. Hope this helps!
