Which number will replace the question mark (?) in the following series?
2, 2, 4, 12, 48, ?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → 240
Each term is the one before it multiplied by 1, 2, 3, 4, 5 in turn:
\(2\times1=2\)
\(2\times2=4\)
\(4\times3=12\)
\(12\times4=48\)
\(48\times5=240\)
So the missing number is 240.
