Answer:
The required sequence is
. The average rate of change from n = 1 to n = 3 is -7.5.
Step-by-step explanation:
From the given graph it is clear that the sequence is a GP because the all terms are half of their previous terms.
Here, 

The common ratio of GP is 1/2.



The first term of the sequence is 20.
The formula for sequence is

Where a is first term and r is common difference.
The required sequence is

The formula for rate of change is

The average rate of change from n = 1 to n = 3 is



Therefore the required sequence is
. The average rate of change from n = 1 to n = 3 is -7.5.
