notice the correlation between the figure number and the number of dots!
number of dots=(fig # +1)!! hence for figure n, the number of dots is n+1! for extra practice, also notice that the number of squares is (figure # x2)-1 :)) for these kind of questions just try to draw and list out the figures after it to notice a pattern :-)
