 The table has 2 columns and 6 rows. The column headers are year and outpatient surgeries performed. The row entries are as follows. Row 1: 1; 45. Row 2: 2; 50. Row 3: 3; 52. Row 4: 4; 56. Row 5: 5; 58. Row 6: 6; blank. 

                            

The director of medical services predicted 6 years ago that demand in year 1 would be 42 surgeries. Using exponential smoothing with a weight of $\alpha =0.20,$  develop forecasts for years 2 through 6. What is the MAD?
