In patterns 1, 2, and 3, describe the growth of the number of toothpicks needed to create the figures while in pattern 4, describe the growth of the number of tiles needed to create the figures.
If yоu hаve а lаrge n x n square with the bоrder squares cоlored red, a way to find the number of red squares could be explained by saying that there are n squares along each of the 4 borders, but the corners are counted twice, so take away the 4 corners. Which expression represents this explanation?
