The following table shows the actual demand observed over the last $4$ years:

$\backslash$table$[[$Year$,1,2,3,4],[$Demand$,8,8,6,7]]$

Using exponential smoothing with $=0\mathrm{.}40$ and a forecast for year $1$ of $7\mathrm{.}0,$ provide the forecast from periods $2$ through $5($round your responses to one decimal place$).$

$\backslash$table$[[$Year$,1,2,3,4,5],[$Forecast $($ES$),7\mathrm{.}0,,,,]]$

Provide the forecast from periods $2$ through $5$ using the naive approach $($enter your responses as whole numbers$).$
