Answer:

<em>5,9,13,17,21</em>

Step-by-step explanation:

We can the values in "n"

a(1)=4(1)+1

a(1)=5

a(2)=4(2)+1

a(2)=9

a(3)=4(3)+1

a(3)=13

a(4)=4(4)+1

a(4)=17

a(5)=4(5)+1

a(5)=21

As you can see, each value consecutively increases by 4, this is also known as the common difference (d).

The table below shows the value of Henry's car at the end for each of the first 3 years after it is purchased. The values form a
SVETLANKA909090 [29]

Using a geometric sequence, it is found that the approximate value of the car at the end of the 10th year will be given by:

A. $6,974.

<h3>What is a geometric sequence?</h3>

A geometric sequence is a sequence in which the result of the division of consecutive terms is always the same, called common ratio q.

The nth term of a geometric sequence is given by:

a_n = a_1q^{n-1}

In which a_1 is the first term.

In this problem, the first term and the common ratio are given, respectively, by:

a_1 = 18000, q = \frac{16200}{18000} = 0.9

Hence the equation is:

a_n = 18000(0.9)^{n-1}

At the end of the 10th year, the value will be of:

a_{10} = 18000(0.9)^{10-1} = 6974

Hence option A is correct.
