I have the following header:
Ene-08 Feb-08 Mar-08 Abr-08 May-08 Jun-08 Jul-08 Ago-08

with data.

If I ad a trendline that gives me an equation, lets say: y=-3242x+13

Being x the month, if I want to get data for month Sep-08, what value should
I use for x=9?

Is that applicable for all the months coming, lets say next february 09
would be x=14?
