Find the difference between consecutive terms: 3-0=3, 8-3=5, so far the differences are odd numbers going up by 2 each time (3, 5, 7, 9, 11...). Continuing this pattern: next difference is 7, so missing term = 8+7 = 15. Check onward: 24-15=9, 35-24=11, 48-35=13 — all fit the same +2 pattern. So the answer is 15, option (2).
PRO TIP
Re-check your working by substituting the answer back into the original question.
