Identify the next two numbers in the following sequence:

17, 20, 9, 12, 5, 6, 3, 2, ____, ____

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
