The number of items sold over a four-month period are:

month	1	2	3	4
sales	5100	5500	5400	5600

Calculate the forecasts for the 4th and 5th months using 3-month weighted moving average method with weights of 0.6 for the most recent month and 0.3 for the next to the most recent month. Further, suppose that the exponential smoothing constant =0.5. Then calculate the forecasts for 3rd, 4th and 5th months, using exponential smoothing method.

Under the 3-month weighted moving average method, what isthe forecast for the fourth month?
