For Growth formula, Y = b*m^X It represents an exponential curve in which the value of Y depends upon the value of X, m is base with X as its exponent, and b are constant. GROWTH is evaluated by calling the related function, LINEST. The population of Flagstaff in 2013 would be 69,080 people. Microsoft recommends replacing FORECAST with FORECAST.LINEAR, since FORECASTwill eventually be deprecated. Linear growth has the characteristic of growing by the same amount in each unit of time. Example In the example shown above, the formula in cell D13 is: = FORECAST.LINEAR (B13, sales, periods) where sales (C5:C12) and periods (B5:B12) are named ranges. Copy the example data in the following table, and paste it in cell A1 of a new Excel worksheet.
