A series is given with one term missing. Choose the correct alternative from the given ones that will complete the series.
12,24,72,288,?
- A1440
- B3250
- C3025
- D2025
Solution & Step-by-step Explanation
Let's look at the multiplication pattern between consecutive terms of the series:
12×2=24
24×3=72
72×4=288
Following this increasing multiplier pattern (×2,×3,×4,…), the next term must be multiplied by 5:
288×5=1440
Thus, the missing number is 1440.
12×2=24
24×3=72
72×4=288
Following this increasing multiplier pattern (×2,×3,×4,…), the next term must be multiplied by 5:
288×5=1440
Thus, the missing number is 1440.
