In the sequence (11,22,33,44,\ldots), which term is (99)?

Answer and explanation

Correct answer: ninth term

Each term in the sequence is a successive multiple of 11, so its nth term is \(a_n=11n\). Putting \(11n=99\) gives \(n=9\). Therefore, 99 is the ninth term. The eighth term is 88, so it is not correct. Exam tip: for such sequences, divide the given term by the common multiple to check its position.
