Which sequence has common difference (0)?
Answer and explanation
Correct answer: (11,11,11,11,\ldots)
In the sequence (11,11,11,11,\ldots), every term is equal to the preceding term. Therefore, the common difference is \(d=11-11=0\). Option B has common difference \(-5\), not zero. Exam tip: To find the common difference of an AP, subtract the first term from the second term.
