14. The answer is A; 8 is the opposite reciprocal of -1/8, which is what you need for perpendicular slope.
15. The answer is C; you can guess and check by plugging points into the equation.
Answer:
for 
Step-by-step explanation:
Given
-- First Term
--- half common difference
Required
Find the recursive rule
First, we calculate the common difference

Multiply through by 2


The second term of the sequence is:

The third term is:

So, we have:


Substitute f(1) for 3

Express 1 as 2 - 1

Substitute n for 2

Similarly:

Substitute f(2) for 11

Express 2 as 3 - 1

Substitute n for 3

Hence, the recursive is:
for 
2x^2=2
x^2=1
x=+ - 1
now u can make graph
