Final answer:
The given sequence 2, 5, 8, 11, 14,... is an arithmetic sequence with a common difference of 3.
Step-by-step explanation:
The given sequence is 2, 5, 8, 11, 14,... It is an arithmetic sequence because there is a common difference between each consecutive term. To find the common difference, we subtract any two consecutive terms. For example, subtracting the second term (5) from the first term (2) gives us 3. Therefore, the common difference is 3.
