Each row in a window display of compact disk cartons contains two more boxes than the row above. The first row has one box. How many rows will make to where there is 144 boxes

Respuesta :

There will be 12 rows when the boxes reach 144. It's basically a pattern that is increasing by 2 each time.

1 + 3 + 5 + 7 + 9 + 11 + 13 + 15 + 17 + 19 + 21 + 23 = 144 boxes

That answers your question! :)
