    Or you could work with moving averages:
    Plot 3 monthly moving averages... extend the trend line/curve and use your next predicted moving average to find the predicted monthly figure and so on.

    I would use a two or three quarter moving average. I wouldn't use a regression line because there doesn;t seem to be an obvious linear relationship looking at that data.

    you can use this tool:

    http://home.ubalt.edu/ntsbarsh/Busin.../ForecaSmo.htm

    with period 3 for a 3 month moving average etc.

    obtain the "forecast" value and add it to the data then run again to get the second predicted value
