Answer:
Step-by-step explanation:
We are given the recursive formula:
This is the recursive formula for an arithmetic sequence.
The explicit formula for an arithmetic sequence is given by:
Where d=3 is the common difference.
We plug in this values to get:
We now expand and simplify to get:
We simplify to obtain:
Answer:
slope =
Step-by-step explanation:
Given the two points on the graph: (-1, 2) (-5, -3)
Let (x1, y1) = (-1, 2)
(x2, y2) = (-5, -3)
We can use the following slope formula:
Substitute the values into the slope formula:
Therefore, the slope of the line is:
