Question

What is the common difference of the arithmetic sequence? 2, 5, 8, 11, 14, ... A) −12 B) −3 C) 3 D) 12

Answer 1

C) 3

Explanation:

The common difference can be found when you find the number that enables the jump to the other. In this case, it is a positive 3, as you add 3 each time:

2 + 3 = 5

5 + 3 = 8

8 + 3 = 11

11 + 3 = 14

etc.
