-3, 1, 5, 9, ... Which function can be used to determine the nth term of the sequence?
A f(n) = n - 3
B. f(n) = n + 4
c. f(n) = 4n - 3
D. f(n) = 4n - 7

D

Step-by-step explanation:

f(n) = -3 + (n - 1)·4

f(n) = -3 + 4n - 4

f(n) = 4n - 7

-3 derives from being the first number in the sequence

4 derives from being the positive difference between values in the sequence

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540
