Identify which among the given numbers in the option is not a term of the sequence $3,7,11,.....$

Therefore, difference between two consecutive terms is same 

So, the given sequence forms an A.P
The common difference of the AP is $7-3=4$.
Let $184$ be the $n^{th}$ term.
Then $184=3+$ $(n-1)\times 4$
$\Rightarrow \frac{181}{4}=(n-1)$
$\Rightarrow n=45.25+1=46.25$
Since, $n$ is not a whole number. $184$ is not the term of this series.
