A series is given with one term missing. Select the correct alternative from the given ones that will complete the series.
60, 121, 243, ?
- A480
- B487
- C484
- D486
Solution & Step-by-step Explanation
Let's find the pattern between consecutive terms in the series:
60×2+1=120+1=121
121×2+1=242+1=243
Following the same logic, the next term will be:
243×2+1=486+1=487
Therefore, the missing term is 487.
60×2+1=120+1=121
121×2+1=242+1=243
Following the same logic, the next term will be:
243×2+1=486+1=487
Therefore, the missing term is 487.
