Question

A matrix of certain characters is given. These characters follow a certain trend, row-wise or column-wise. Find this trend and choose the missing character from the given alternatives.

1	4	9	?
1	2	3	4
2	4	6	?

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

Answer 1

The correct option is A $16,8$

Let $x$ represents a number in the second row. Then, corresponding number in the first row is represented by $x^2$ and that in the third row by $2x$.
So, missing number in the first row $=4^2=16$
And, missing number in the third row$=2\times 4=8$
Hence, option (A) is the correct answer.
