Question: Write the mathematical formulation for the random walk with the drift model. What would be the expectation, computed in period t, of the time series

Write the mathematical formulation for the random walk with the drift model. What would be the expectation, computed in period t, of the time series y two periods from now (ie, in period t+2t)? What would be the error you made (ie what is the difference between yt+2 and its expectation)?
