Growth

[slarson]

I am tryig to enter an array for growth calculations.Jan-
Dec for known x values and their corresponding $ amounts
for the known y values. For unknown x values I enter the
concurrent Jan to whenever to calculate the growth. I am
not getting the proper returns.

What am I doing wrong?

Thanks.

Look at linest, trend, Logest, forecast and the intercept and slope
functions.
