In the given question,the given explicit formula is

Which is of the form

So the constant difference is 7 here.
Now for the recursive formula
To find the next term, we need to add 7 to the current term, that is

So the correct option is B
81- answer is ok but im not suree
Answer: $50
Step-by-step explanation: Draw a line through the apparent center of the scattered dots. See where that line intersects 9 in the time scale (x-axis numbers) and the dollars earned scale (y-axis numbers)
It could be 50 or 55, but since there are a few more dots below the apparent midline, it may be best to use the lower estimate.
Your x-intercept is at (-2,0) and your y intercept at (0,-3), so it's D
