Question

Find the missing term.

$13$	$54$	?
$7$	$45$	$32$
$27$	$144$	$68$

• A. $42$
• B. $36$
• C. $6$
• D. $4$

Answer 1

The correct option is D $4$

Here in a column we add first two elements and then add the second element once more.The sum is nothing but the third element in that column.

In first column

$=13+7+7=27$
In second column

$=54+45+45=144$
In third column

$=4+32+32=68$

Hence, option D.
