If we fit a linear trend to 10 observations on time-series data that are growing exponentially, then it is most likely that: the fitted trend will be too high at t = 1 and t = 10. the fitted trend will be too low in the middle. the forecasts (if extrapolated) will be too low. the residuals will show a pattern like - - - + + + + - - -.
