Question

Exponential smoothing with trend, with a smoothing constant of α = 0.2 and a trend smoothing constant of β = 0.3, is being used to forecast values in a time series. At this point, the last two values have been 535 and then 550. The last two forecasts have been 530 and then 540. The last estimate of the trend factor has been 10. Use this information to forecast the next value in the time series. (Use hand calculations rather than an Excel template.)
