B Using the same sets of numbers in Exercise A, indio arithmetic sequences and the common ratios (n) of the your answer are (7) common difference or (r) common ra 4 5.
The common difference is the value between each successive number in an arithmetic sequence. Therefore, the formula to find the common difference of an arithmetic sequence is: d = a(n) - a(n - 1), where a(n) is the last term in the sequence, and a(n - 1) is the previous term in the sequence.
