Estimate next values

Hi, I don't know if this is an Excel or Stats or Math question, but I need to fill in the blanks here:

I need to determine growth rate based on this trend.
If possible, I would like to know thought process/formula.

Also, it would be nice to know on what date it would hit 2,000,000... 2,400,000???

Thank you very much in advance...

To calculate growth, put in the cell after 1,200,000 this formula:

= (B2/B1-1)/(A2-A1)

and format it as percent.

B2 is 1,200,000
B1 is 1,000,600
A1 is 11/6/08
A2 is 2/26/09

Hi, Thanks for that, but I am not sure if that was what I needed.
Basically, the stats I have are for dates of very different intervals. Historically, some 1 month periods show a growth of 400,000; however, some show 30,000. I remember there was a formula that takes care of this, but it has been a while.
