Question

Find the odd man out from the given series.

$4,12,30,68,146,302,622$

• A. $12$
• B. $30$
• C. $68$
• D. $302$

Answer 1

The correct option is D $302$

The series is written using the pattern
$4\times 2+4=12$,
$12\times 2+6=30$,
$30\times 2+8=68$,
$68\times 2+10=146$,
$146\times 2+12=304$,
$304\times 2+14=622$.
Therefore, Number 302 should be replaced by 304.
