-Lets say that the question is asking for us to forecast
using MA3 for the next month (t+1) and the next 2 month
(t+2) however the question only provided us data with the real
values up until month t. We can forecast for month t+1 because the
real values up until month t are provided to us , however how do we
forecast for month t+2 if we do not have the real value for
t+1?
