Extrapolate the trend?

Just doing a question on the above budgeting topic and am alittle confused, specially as my osborne book doesnt really cover what extrapolate means.

Basically i have a sales forcast for 9 months of the year and the seasonal variation in given as well. ie. January sales forecast of 80 and a seasonal variation of -40. I am assuming the trend for each month would be the difference between the forecast and the seasonal variation. The last 3 months of the year are blank except the seasonal variations.

The question im stuck on is just "extrapolate the trend"... what does this mean? Just predict the last 3 months trend figures? I can see that every month the trend goes up by 2.5 units.

Cant any one shed some light please??

    "calculate an amount, based on other calculations. maths to calculate an amount that you do not know by basing your calculations on amounts that you already know"

    so yes, I would say you are to calculate the last 3 months of the year, based on the figures you are given.
