Question and options
Find the next number in the sequence:
3, 6, 9, 30, 117, __________
3, 6, 9, 30, 117, __________
- 192
- 352
- 388
- 588
Answer and explanation
Correct answer: D - 588
The rule alternates: multiply by 1 and add 3, multiply by 2 and subtract 3, multiply by 3 and add 3, multiply by 4 and subtract 3. So 3 → 6 → 9 → 30 → 117, and the next step is 117 × 5 + 3 = 588.
