f(x) = 6x − 2
f(x) = 6x − 2
f(x) = 6x − 2

2, 8, 12, 20, 26
2, 8, 12, 20, 26
2, 8, 12, 20, 26

an = −5 + 6(n − 1)
an = −5 + 6(n − 1)

Answer 1

The sequence 2, 8, 12, 20, 26 is unlike the others with respect to the rate of change. The common difference between consecutive terms is not constant in this sequence, while in the other two sequences the common difference is 6.
