Here's a really simple solution: Load the data into R using read.table (this may involve cleaning up the dollar amounts). It looks linear (scatterplot of revenue and quarter_index), so fit a linear model (Revenue ~ quarter_index) with lm(). Use the object created and a dataframe of what values you want to predict (probably quarter_index=seq(1,16)) with the predict() command. For a bit more information, see http://cran.r-project.org/doc/manuals/R-intro.html#Linear-models and the following section. Also try ?lm, ?predict. (On a side note, my predicted values are consistently about $50,000 higher than the ones you got from what were using. Since I don't know what exactly your tool is doing, I can't tell you why that is). If you want to take into account the fact that it's actually a time series, R has plenty of tools for that too.
