Answer and explanation
Correct answer: 22
This is an arithmetic progression with common difference \(d=7-2=5\). Using \(a_5=a_1+(5-1)d\), we get \(a_5=2+4\times5=22\). Therefore, option C is correct. Exam tip: when the consecutive difference is constant, add the common difference to obtain the next term.
