Solution
Exponential smoothing forecasts uses a simple formula as given below
Forecasted value of current period = Forecasted value of previous period + alpha times the difference between the actual and forecasted values of previous period
One can use scientific calculator or excel to make use of the above mentioned formula repeatedly to get the forecasts.
