Bobby the fly starts at the point (0,0) in the coordinate plane. At each point, Franklin takes a step to the right, left, up, or down. After 12 steps, how many different points could Franklin end up at?

1 step  =  4 points

2 steps  = 9 points

3 steps = 16 points

n steps  = (n + 1)^2  points

 

12 steps  = (12 + 1)^2  =  169 points
