After plotting the following demand data a manager has concluded that a trend-adjusted exponential smoothing model is appropriate to predict future demand.

Use period 1 to 4 to estimate the initial smoothed trend and the actual value for period 4 to estimate the initial smoothed series. use alpha= 0.5 and beta=0.3 to develop forecasts for periods 5 through 7
