Find the number which does not fit into the series given below.
3, 6, 12, 22, 48, 96, 192
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → 22
Most terms are twice the term before, so check each step against this rule:
\(3\times2=6\), \(6\times2=12\)
\(12\times2=24\), but the series has 22
\(24\times2=48\), \(48\times2=96\), \(96\times2=192\)
All the other terms fit if the fourth term is 24. So 22 does not fit the series.
