Activity 7:       To observe the following number patterns and generate it up to next three steps


i)                        12 =                          1

                                      112 =              1          2          1

                                    1112 =  1          2          3          2          1


ii)                   1+3         = 4     =  22

1+3+5     = 9     = 32

1+3+5+7 = 162 = 42
