Which function can be used to find the nth term of the arithmetic sequence?

A.
f(n) = n + 4

B.
f(n) = -n

C.
f(n) = 0.5(n + 5) + 2

D.
f(n) = -3n + 8

Respuesta :

Answer:

D

Step-by-step explanation:

d is the only choice that will give the numbers for the terms

f(n)=-3n+8

f(1)=-3(1)+8  f(1)=5

f(3)=-3(3)+8  f(3)=-1

f(10)=-3(10)+8  f(10)=-22
