The table below is the data set of the number of preorders received for a particular game on a weekly basis.

The forecaster uses the Holt-Winters Exponential Smoothing for nonseasonal series to forecast the number of preorders in future time periods.

He uses α = 0.8 and β = 0.5. (Hint: Use the formula from the text to arrive at the answers.)
