Answer:
C) ƒ(x) = −3x + 4
Step-by-step explanation:
The arithmetic sequence has a general form:
f = a + d(x-1)
Where: a is the first term and d is the common difference
For the given arithmetic sequence :
1, −2, −5, −8, −11, ...
a = 1
d = -2 - 1 = -3
So, f(x) = 1 + (-3)(x-1)
∴ f(x) = 1 -3x + 3
∴ f(x) = -3x + 4
The answer is option C) ƒ(x) = −3x + 4
