Answer:
A
Step-by-step explanation:
A recursive formula allows the term in a sequence to be obtained from the previous term.
To find any term in the sequence multiply the previous term by the common ratio r
r = - 6 ÷ 2 = 18 ÷ - 6 = - 3
Thus the 9 th term can be found using
f(9) = f(8) × - 3 = - 3f(8) → A

Answer:
The easiest approach is to realise that one hour is 3 times longer than 20 minutes. The longer the time, the more they will pave.
215 of a mile, in 20 minutes, how much in 60 minutes?#
They will pave 3 times more.
215×31=615 of a mile
615=25 of a mile
You could also use the 'unitary method' where you find out how much they pave in ONE minute (divide by 20) and them multiply by 60 to find how much in one hour.
Look at what happens:
215÷20×60
=215×120×603
=215×3 ← exactly the same maths.
=25
To set the equation,we can first find how much price would be raised within a year:
=500×(1+7%)
=500×1.07
As the years go by the increase would accumulate,and the equation would be:
