9a) Each step in the pattern creates a large square in which the side length is one square greater than the previous square. So, the total number of small squares in each large square is the next larger perfect square.

9b)The pattern is continued by adding n squares to the bottom row, n squares along the right column, and then one square to fill in the corner. This is a total of n+n+1 squares, or 2n + 1 squares. The expression 2n+1 is a way of representing odd integers.
