The difference between any two consecutive terms of an arithmetic sequence is the common difference, which is the fixed value that is added (or subtracted) from one term to the next to produce the sequence. For example, in the arithmetic sequence 2, 5, 8, 11, 14, the common difference is 3 because each term is obtained by adding 3 to the previous term. Thus, the difference between any two consecutive terms (e.g., between 5 and 8) is also 3.
