Find the number that will come next in the series given below.
2, 4, 12, 24, 72, ?
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → 144
Compare each term with the one before. The terms are multiplied by 2 and by 3 alternately:
\(2\times2=4\), \(4\times3=12\)
\(12\times2=24\), \(24\times3=72\)
The next step is ×2: \(72\times2=144\)
So the next number is 144.
