Answer: 177.5
Step-by-step explanation:
The forecast for period 5 using the Exponential Smoothing formula is;
F( t + 1 ) = Ft + a ( At - Ft )
Where,
a is the smoothing constant
At is the actual demand for the preceding period
Ft is the forecasted demand for the preceding period
= F4 + a ( A4- F4 )
= 190 +0.5 ( 165 - 190 )
= 177.5
