The common difference of the arithmetic sequence 2, 5, 8, 11 is 3.
The common difference in an arithmetic sequence is the constant value added to each term to get the next term. To find the common difference, subtract any term from the term that follows it.
- 5 - 2 = 3
- 8 - 5 = 3
- 11 - 8 = 3
As the reference states, "Notice that the difference between each consecutive term in this sequence is 3. Therefore, this is an arithmetic sequence with a common difference of 3."
