Question

Find the missing term in the given figures.

1	7	6
3	3	?
5	4	8
35	74	104

• A. $1$
• B. $2$
• C. $3$
• D. $4$

Answer 1

The correct option is B $2$

First column: $1^2+3^2+5^2=1+9+25=35$
Second column: $7^2+3^2+4^2=49+9+16=74$
Third column: $6^2+8^2=100$
Now, 104 - 100 = 4 which is nothing but square of 2.
Hence, option (B) is the correct answer.
