Sequence Question:
Identify the next two numbers in the sequence:
17, 20, 9, 12, 5, 6, 3, 2, ?, ?
Solution:
Let’s split the sequence into two alternate parts:
- Odd-positioned terms: 17, 9, 5, 3 → decreasing by 8, 4, 2
- Even-positioned terms: 20, 12, 6, 2 → decreasing by 8, 6, 4
Continue the pattern:
- Odd series: 17 → 9 (–8), 9 → 5 (–4), 5 → 3 (–2), so next is 3 – 1 = 2
- Even series: 20 → 12 (–8), 12 → 6 (–6), 6 → 2 (–4), so next is 2 – 2 = 0
✅ Final Answer:
2, 0
