Answer:

f(n) = -7+3n

Step-by-step explanation:

I plugged the values into the equation and they work.

f(n) = -7 + 3(10) = 27

f(n) = -7 + 3(12) = 26

f(n) = -7 + 3(16)= 32

Solve the equation.
Vinil7 [7]
If you would like to solve the equation x + 1/6 = 6, you can do this using the following steps:

x + 1/6 = 6       /-1/6
x + 1/6 - 1/6 = 6 - 1/6
x = 6 - 1/6
x = 36/6 - 1/6
x = 35/6
x = 5 5/6

The correct result would be C. x = 5 5/6.
