Find the wrong number in the given series.
4, 10, 22, 46, 96, 190, 382
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → 96
Each term is twice the previous term plus 2:
\(4\times2+2=10\), \(10\times2+2=22\), \(22\times2+2=46\)
\(46\times2+2=94\), but the series has 96
\(94\times2+2=190\), \(190\times2+2=382\)
The later terms 190 and 382 fit only if the fifth term is 94, so 96 is the wrong number.
