In the AP (-25,-14,-3,\ldots), what is the first term greater than (200)?

Answer and explanation

Correct answer: 206

Here, the first term is \(a=-25\) and the common difference is \(d=11\). Thus, \(a_n=-25+11(n-1)=11n-36\). For \(a_n>200\), \(11n-36>200\), so \(n>21.45\). The smallest integer value is \(n=22\), giving \(a_{22}=206\). The value \(195\) is the preceding term, \(a_{21}\), so it is not greater than 200. Exam tip: For a “first term greater than” question, take the smallest integer satisfying the inequality.
