Budgeting - Forecasting trends

Kelly20

Hello, so I have the following question -

Sales of product x are growing by 2% per quarter. For quarter 4 of the current year sales were 50,000 units.

Complete the table below to forecast the trend for each of the next 4 quarters and then adjust your figures for seasonal variations to give a forecast for actual sales. (Round to the nearest whole number)

Q1 Q2 Q3 Q4
Trend
Seasonal Variations -5% -10% +2% +13%
Forecast


Not sure if I am just over thinking this! But I can't seem to get my head around how to work any of this out, it feels like there is not enough info.

Any help appreciated
