Can you help solve a linear regression forecasting for at least 6 more quarters using excel functionalities? The table of values is really just market share (in %) for the vertical axis and the quarters, beginning 1st quarter 2015 up to 2nd quarter 2019. I want to get the forecasts for the next 6 quarters, using excel solver for linear regression.

Quarters 1st Qtr 2015 2nd Qtr 2015 3rd Qtr 2015 4th Qtr 2015 1st Qtr 2016 2nd Qtr 2016 3rd Qtr 2016 4th Qtr 2016 1st Qtr 2017 2nd Qtr 2017 3rd Qtr 2017 4th Qtr 2017 1st Qtr 2018 2nd Qtr 2018 3rd Qtr 2018 4th Qtr 2018 1st Qtr 2019 2nd Qtr 2019
