What is the pattern in the sequence graphed below?
a. multiply the term number by –1, then add 8.
b. multiply the term number by –1, then add 9.
c. add 8 to the term number, then multiply by –1.
d. add 9 to the term number, then multiply by –1.

b.Multiply the term number by –1, then add 9.

Step-by-step explanation:

If we look at the graph, we can see that it is decreasing at a constant rate. This means same pattern is happening at each step.

The correct pattern here is option B

Multiply the term number by –1, then add 9.

We can check this. Say to get 3 at x- axis, we will find like:

Similarly, to find 8 at x -axis, we will calculate:

Therefore, option B is correct.

Options C and D will give negative numbers as anything multiplied by -1, will give negative numbers.
