Step-by-step explanation:
A simple fraction (also known as a common fraction or vulgar fraction, where vulgar is Latin for "common") is a rational number written as a/b or {\displaystyle {\tfrac {a}{b}}}
b

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.
