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 should be double the one before it: 7, 14, 28, 56, then 112, then 224.
The number printed in the fifth place is 102 instead of 112, so it breaks the pattern and is the odd one out — the following term, 224, confirms it, being twice 112.
