What is the next term in the sequence (5,11,19,29,41,\ldots)?

Answer and explanation

Correct answer: 55

The differences between consecutive terms are \(11-5=6\), \(19-11=8\), \(29-19=10\), and \(41-29=12\). These differences increase by 2 each time, so the next difference is \(14\). Therefore, the next term is \(41+14=55\). Choosing 54 would give a difference of 13, which does not follow the pattern. Exam tip: For a sequence, first list consecutive differences and check their pattern.
