x + (x + 2) + (x + 4) + (x + 6) = 156
       x + x + x + x + 2 + 4 + 6 = 156
                                 4x + 12 = 156
                                       - 12   - 12
                                         4x = 144
                                          4        4
                                           x = 36
       x = 36
x + 2 = 38
x + 4 = 40
x + 6 = 42
