Hi!
First find how much you were off by.
14-12=2
Now set up a proportion and cross multiply to solve.

2 x 100 = 200
200/14 = 14.29
The answer is
14.29%
B is the correct answer 'friendship'
Answer:
D] f(n) = f(n − 1) + (−7)
Step-by-step explanation:
since you already know is an arithmetic series, you have to find the common difference.
87 - 94 = -7
80 - 87 = -7
73 - 80 = -7
the formula for the nth term is f(n) = f(n-1) + d
where f(n-1) is the previous term and d is the common difference, so if youu substitute you get:
f(n) = f(n-1) + d
f(n) = f(n-1) + (-7)
