Which term is not given in the arithmetic progression (18,21,24,27,\ldots)?
Answer and explanation
Correct answer: 30
The explicitly listed terms are 18, 21, 24 and 27. The common difference is \(21-18=3\), so the next term would be \(27+3=30\). Therefore, 30 is a term of the AP but is not among the terms given in the question. Exam tip: distinguish the terms already listed from the terms that can be generated next.
