2	4	6	?

• A. $16,8$
• B. $49,7$
• C. $36,4$
• D. $25,5$

Answer 1

The correct option is A $16,8$

Each row follow some pattern :

First row,

$1^2=1$,

$2^2=4$,

$3^2=9$,

So $4^2=16$.

Thus first missing term is $16$.

3rd row,

$2\times 1=2$,

$2\times 2=4$,

$2\times 3=6$,

So, $2\times 4=8$.

Thus 2nd missing term is $8$.

Hence $16,8$ replaces question mark.
