Complete the following series.
9, 12, 18, 30, 54, ?
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → 102
The differences between consecutive terms double each time.
Differences: \(12-9=3\), \(18-12=6\), \(30-18=12\), \(54-30=24\)
The next difference is \(24\times2=48\)
Next term \(=54+48=102\)
