Which of the following is UNLIKE the others with respect to the rate of change?

Responses

f(x) = 3x − 2
f(x) = 3x − 2

−3, 1, 5, 9, 13, 17
−3, 1, 5, 9, 13, 17

an = 3 + (n − 1)(4)
an = 3 + (n − 1)(4)

f(x) = 4x − 2
f(x) = 4x − 2

The third option, "an = 3 + (n − 1)(4)", is unlike the others with respect to the rate of change. The other options represent linear functions with a constant rate of change, while this option represents a sequence with a constant difference of 4 between consecutive terms.
