Which sequence has common difference (6)?

Answer and explanation

Correct answer: (1, 7, 13, 19, \ldots)

In the sequence (1, 7, 13, 19, \ldots), the differences between consecutive terms are 7−1=6, 13−7=6, and 19−13=6. Therefore, its common difference is \(d=6\). Option C has common difference \(-6\), so it is not correct. Exam tip: subtract the first term from the second term to find the common difference.
