Question

Find the missing term :

$6$	$11$	$25$
$8$	$6$	$16$
$12$	$5$	?

• A. $18$
• B. $16$
• C. $12$
• D. $10$

Answer 1

Answer: (B)

$16$

Here we have a algorithm that in a row first element in a row is divided by 2 where as second element is multiplied by 2.

The sum of these two resultant is equal to the third element in a row.

This is followed in all rows.
As in first row

$11\times 2+\frac{6}{2}=25$
In second row

$6\times 2+\frac{8}{2}=16$
In third row

$5\times 2+\frac{12}{2}=10+6=16$.

Hence option B is the correct answer.
