please need steps for each answer

a) Using a 2-year moving averape, the forecast for year 6 miles (round your response fo the noarest whole number). b) If a 2-year moving average is used to make the forecast, the MAD based on this =125.0 miles (round your response fo one decimai place). (Hint: You wwll have any 3 youns of mitched datas) c) The forecast for year 6 using a weighted 2-year moving average with weights of 0.40 and 0.60 (the weight of 0.60 is for the most recent period) = 3 sezo mies (round your response io the neirest whole numberf. The MAD for the forecast developed using a weighted 2-yeat meving average with weights of 0.40 and 0.60=163.3 miles (pound your rosponse to one decina place) itent You wit have any 3 . years of matched data.) d) Using exponential smoothing with =0.20 and the forecast for year 1 being 3,100 , the forecast for year 6=3,002 miles (round your response to the nearest whals number
