Answer 1

To complete the missing values in the table using the arithmetic sequence formula, we substitute the values of 'n' into the formula to find the corresponding values of 'y':

For n = 2:
an = 5 + (2 - 1) * 2
= 5 + 1 * 2
= 5 + 2
= 7

For n = 4:
an = 5 + (4 - 1) * 2
= 5 + 3 * 2
= 5 + 6
= 11

So, the completed table is:

x y
2 7
4 11

Answer 2

Use the image to answer the question.

Four different configurations of tiles are labeled 1–4.

Analyze the tile pattern and write a function for the pattern. Use x for the image number and y for the number of tiles in each image.

(2 points)
The function modeled by the pattern is
, since the slope is
and the y-intercept is
.
