A. an = 3n+1

E. None of the choices

C

Step-by-step explanation:

The relationship is linear and of the form

y = mx + c

m =

with (x₁, y₁ ) = (3, 1 ) and (x₂, y₂ ) = (5, 5) ← 2 ordered pairs from the table

m = = = 2 , then

y = 2x + c

To find c substitute any ordered pair from the table

Using (7, 9 ) , then

9 = 14 + c ⇒ c = 9 - 14 = - 5

y = 2x - 5 , that is

= 2n - 5 → C

credit scoring calculations, such as the fico score, look at a few key factors related to your debt. the amount of overall debt you carry, the ratio of your credit card balances to your credit limit (also called credit utilization), and the relation of your loan balances to the original loan amount.
