i) If we believe that a time series follows an AR(1) with=.9 and an intercept value of .4, the last recorded values of the time series were 5 (time t-1) and 5.4 (time t-2), and the last observed innovations (errors) were .3 (time t-1) and -.4 (time t-2), what is the model forecast for the coming period (time t)? For the period after that (time t+1)?
