Which of the following numbers will replace the question mark (?) in the given series?
14, 14, 12, 36, 32, 160, ?
150
166
154
145
Alright, let’s break this sequence down:
- The given series is: 14, 14, 12, 36, 32, 160, ?
- Let’s look for a pattern. It seems to alternate:
- 14 ? 12 (subtract 2)
- 14 ? 36 (multiply by 2.57?) – not clean.
- 12 ? 32 (add 20), 36 ? 160 (multiply by a bit over 4)
- Another way: Odd and even positioned terms might each have their own patterns.
- Odd positions: 14, 12, 32, ?
- 14 ? 12 (–2), 12 ? 32 (+20), so next one: 32 + 20 = 52
- Even positions: 14, 36, 160
- 14 ? 36 (x2.57), 36 ? 160 (x4.44), not a clear multiplier.
- But watch this:
- 14, 14 (no change)
- 14 × 1 = 14
- 14 – 2 = 12
- 12 × 3 = 36
- 36 – 4 = 32
- 32 × 5 = 160
- 160 – 6 = 154
- So the rule is: alternate "multiply by an odd number" and "subtract the next even number."
- 14 (start)
- Option 3: 154
- This fits perfectly.
- Other options don’t fit this rule.
