Expert Solution
Step 1

The Holt's Forecasting for the period t+1 is given as: Ft+1=Lt+Tt

Where, Lt, i.e., the current level value, which is defined with the smoothing parameter for level α. 

And Tt, i.e., the current trend value, which is defined with the smoothing parameter for trend β.

In general, for the forecast horizon of n period, Holt's forecast model is given as: Ft+n=Lt+nTt.
