Last Updated On: Sat Aug 29 2026Given Series
- Given number series: 14, 28, 20, 40, 32, 64, ?
Question
Determine the next term in the series.
Answer
56.
Solution
- Analyze the operations connecting alternate terms or consecutive pairs:
- 14 × 2 = 28
- 28 - 8 = 20
- 20 × 2 = 40
- 40 - 8 = 32
- 32 × 2 = 64
- Pattern rule alternates between multiplying by 2 (× 2) and subtracting 8 (- 8).
- Next operation is -8.
- Next term = 64 - 8 = 56.
