Draw the 3rd and 5th figures.
Can you see a pattern in the completed figures? Use this pattern to complete figures 3 and 5.
How many dots will there be in the 50th figure?
The number of dots in a figure is described by the equation # of dots = 2 + 2x where x is the figure number. Plug in x = 50 to find the answer.
Is there a figure that will have exactly 38 dots? If there is, which figure is it?
for ''# of dots'' in the equation above, then solve for x. If you get a whole number, that is the figure number.
