You then adjust for the seasonality by multiplying the trend forecast by 95%.You then repeat this for Q4 and then you can calculate the increase in sales.
I assume that you have watched my free lectures on time series analysis? The lectures are a complete free course for Paper F2 and cover everything needed to be able to pass the exam well.
