Which of the following sets of data points represents a linear pattern?

(0, 2), (1, 5), (2, 9), (3, 14)

(0, 1), (1, 4), (2, 9), (3, 16)

(0, 5), (1, 9), (2, 13), (3, 17)

(0, 10), (1, 8), (2, 5), (3, 0)

A data set is analyzed and the first differences are calculated as $6, 7, 8$. Does this data represent a linear pattern?

Yes, because the differences are positive.

No, because the first differences are not constant.

Yes, because the differences are consecutive integers.

No, because the differences must be negative.
