Final answer:
The given set of numbers {5,1, 8,3, 11,7, 14,12} is not linear.
Step-by-step explanation:
The given set of numbers {5,1, 8,3, 11,7, 14,12} is not linear.
In a linear pattern, there is a constant difference between consecutive terms. However, in this set, the differences between the consecutive terms are not the same.
For example, the difference between the first two terms is -4, between the second and third terms is +2, and so on. Since the differences are not constant, the set of numbers is not linear.
