is that for the whole task?0

A ) it is asking you to do the average of 3 months, so you add up the first 3 and divide by 3 (5760+5820+5760)/3 = 5780 then you do the next 3 months (including feb to apr) and divided by 3 again and same for the rest.
B ) 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
140005000 = 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.
