Answer :
The exponential smoothing forecast for subsequent length is 101.6.
The required details for exponential smoothing forecast in given paragraph
Forecasts produced the usage of exponential smoothing strategies are weighted averages of beyond observations, with the weights decaying exponentially because the observations become older. In different words, the extra latest the remark the better the related weight. Exponential Smoothing Methods are a own circle of relatives of forecasting models. They use weighted averages of beyond observations to forecast new values. The concept is to offer extra significance to latest values within side the series. Thus, as observations become older in time, the significance of those values get exponentially smaller.
For any α among zero and 1, the weights connected to the observations lower exponentially as we move again in time, therefore the name “exponential smoothing”. If α is small (i.e., near zero), extra weight is given to observations from the extra remote beyond.
