3.3   Anne and Jerry look at the following patterns:

       Pattern 1                   Pattern 2                    Pattern 3
         ●                           ●●                          ●●●
         ●                           ●●                          ●●●
                                     ●●                          ●●●

      Anne says she can derive the general formula for the number of dots by taking the
      number of columns in each pattern and multiplying it by the number of rows.
      Jerry says if he increases the pattern number by one, squares that and then subtracts the
      pattern number increased by one he will get the general formula.
