Given:

To find:
The recursive formula.
Solution:
We have,

It is in the form of explicate formula of a GP, .i.e.,
.
Here,
and
.
The recursive formula of a GP is

Using this the recursive formula for given problem is

Therefore, the required recursive formula is
.
Answer:
Rate of interest will be 1.33 %
Return on this investment =
%
Step-by-step explanation:
We have given principle amount P = $9000
Time = 61 days = 
We have to find the rate of interest
Total amount produce at the end of term = $9020
So interest = $9020 - $9000 = $20
We know that simple interest 

%
Return on this investment =
%
