Which of the following is UNLIKE the others with respect to the rate of change (common difference)?(1 point)
Responses

f(x) = 6x − 2

f(x) = 6x − 2


an = −5 + 6(n − 1)

an = −5 + 6(n − 1)


2, 8, 12, 20, 26

2, 8, 12, 20, 26


f(x) = 6x +1

Answer 1

2, 8, 12, 20, 26

Reason: f(x)=6x−2, f(x)=6x+1, and a_n = −5 + 6(n−1) all have a constant rate of change (slope/common difference) of 6. The sequence 2, 8, 12, 20, 26 does not have a constant difference (differences: 6, 4, 8, 6).
