In the following series, find the odd one out from the given series: 7, 14, 28, 56, 102, 224
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → 102
Each term of the series is double the term before it:
\(7\times2=14\), \(14\times2=28\), \(28\times2=56\)
The next term should be \(56\times2=112\), not 102, and \(112\times2=224\) fits the last term, so 102 is the odd one out
