Question

One term in the number series is wrong. Find out the wrong term.

• A. $182$
• B. $247$
• C. $232$
• D. $221$

Answer 1

The correct option is A $182$

The given series follow a pattern :

$143+13=156,$

$156+13=169,$

$169+26=195\ne 182,$

$195+26=221,$

$221+13=234,$

$234+13=247$.

Hence, $182$ is wrong in the given series.
