Here are a couple of resources for getting the information about the
trendline via formula.

If I have a set of data, is there any way I can generate a formula which
roughly matches the plot of the data set? I know I can generate a trend line
on a chart but is there a way of finding out the formula for this trendline,
so that I could reproduce it without the origiinal data perhaps?

Hope I'm making myself clear. Many thanks in advance.
