Step-by-step explanation:
Answer:
Step-by-step explanation:
we know that
In a <u>Geometric Sequence</u> each term is found by multiplying the previous term by a constant, called the common ratio (r)
In this problem we have
Remember that
-----> -----> equation A
Substitute the values of a_5 and a_2 and solve for r
Find the value of a_1 in equation A
therefore
The explicit rule for the nth term is
substitute
The answer is D because a proportional relationship on a graph would start on (0,0), so A and B cannot be the right answer. On answer C, the relationship starts as 4x=y but changes, so this cannot be a proportional relationship because the relationship needs to be constant. Answer D is the right answer because the proportional relationship remains constant (1.5x=y).
