Forecast data using Linest functions syntax

[#1]

Hi Guys,

I have scenario,i need to show forecast data.

I am using linest_m and Linest_b functions and able to generate the forecasting piece

=if(Year<=2016,AVG(SalesGrowthRate),(linest_m(total aggr(if(avg(SalesGrowthRate)+$(Sales Annual Growth Rate),avg(SalesGrowthRate)+$(Sales Annual Growth Rate)),Year),Year)*Year

+linest_b(total aggr(if(avg(SalesGrowthRate)+$(Sales Annual Growth Rate),avg(SalesGrowthRate)+$(Sales Annual Growth Rate)),Year),Year)))

But my scenario is the forecasting data is

after 2016 i want show  SalesGrowthRate=SalesGrowthRate+(SalesGrowthRate*($(Sales Annual Growth Rate)))

Can any body send the syntax using lineest_m and linest_b for getting the above logic

Please find the attached excel and qvw for reference

Thanks and Regards
