Correct option is A
Given: 8, 16, 7, 14, 5, 10, 1, 2,?
The logic mentioned is ×2, -9, meaning we alternate between multiplying by 2 and subtracting 9. Let’s apply this step by step:
8 ×2 → 16 (Multiply by 2)
16 – 9 → 7 (Subtract 9)
7 ×2 → 14 (Multiply by 2)
14 – 9 → 5 (Subtract 9)
5 ×2 → 10 (Multiply by 2)
10 – 9 → 1 (Subtract 9)
1 ×2 → 2 (Multiply by 2)
2 → ? (Now subtract 9)
Following the pattern:
2 - 9 = -7
Correct Answer: (a) -7
