Practice objective / multiple choice question 7 from the 2022 Neco Mathematics examination.
The sequence \(\{a_n\}\) satisfies \(a_1 = 5\), \(a_2 = 12\). From the third term onward the sequence is arithmetic; that is, there exists a constant difference \(d\) such that \(a_{n+1}-a_n = d\) for all \(n \ge 3\). If the sum of the first five terms equals 65, determine the value of \(a_4\).
