9494B ) It is normal definition of Seasonal Variations which is it is actuals - trend

The usual increases in November and December are seasonal variations (they are recurring every year for christmasy in this instance)

C ) it is indexes, you have January figure Actual x RTI for January (which it is the base) / RTI the month which are you are calculating

129000 X 170 / 170 for January

132000 x 170 / 172 for Feb

135000 x 170 / 174 for March

D ) y=a+bx is the high low method

x = units

200 units £5000

2000 units £14000

14000-5000 = 9000

2000 - 200 = 1800

9000/1800 = £5 which is b

£5 x 200 = £1000 => £5000 - £1000 => £4000 is the fixed figure

hence a is £4000, b is £5 and x is the units number

Hope this helps.
