In the advanced version we will have a shortcut in the formula bar called more function and follow the below procedure. The TREND function uses the least squares method to find the line of best fit and then uses IT to calculate the new y-values for the provided new x-values. In the chart select the trendline equation. TRENDB2B13A2A13D2 We fixed the range for known values of X and Y and passed the new value of X as a reference value.
