Let plug in the
Forecast for period 2= 0.2 * 7+ (1-0.2)* 5
Forecast for period 2= 5.4 units
Now let determine the Forecast for period 3

Forecast for period 3 = Alpha* Actual demand for period 2 + (1- alpha) * Forecast for period 2
Let plug in the formula
Forecast for period 3= 0.2 * 9 + (1-0.2)* 5.4
Forecast for period 3=6.12units
Therefore what should be the forecast for period 3 is 6.12 units
