Question

Find the wrong term of the series :

$444,300,200,136,87,84,80$

• A. $300$
• B. $200$
• C. $136$
• D. $87$

Answer 1

The correct option is D $87$

Here the difference between the consecutive terms is as: $-144$ (or ${12}^2$), $-100$ (or ${10}^2$), $-64$ (or $8^2$), $-36$ (or $6^2$), $-16$ (or $4^2$) and $-4$ (or $2^2$).
Clearly, $136-36=100$ $\ne 87$.
Hence, option (D) is the correct answer.
