Discussion
The sequence below breaks off before its final term. Establish what governs the terms and give the one that comes next.
5, 6, 11, 20, 33, ?
Answer: C
Correct answer: 50
The gaps are not equal: they run 1, 5, 9, 13, each 4 more than the last. The next gap must therefore be 17, and adding it to the final term, 33 plus 17 is 50. As a check, the gap between the answer and 33 is 17, which continues the run of gaps 1, 5, 9, 13 by a further 4. A second row of differences that is constant confirms the reading, and it is worth writing out before committing to an answer.
