Answer 1

Solution :-

Logic :- Middle term is half of sum of all squares.

In First Square we have,

→ 6 - 2 - 2 - 4 = 30

→ (6)² + (2)² + (2)² + (4)²

→ 36 + 4 + 4 + 16

→ 60

→ 60 ÷ 2

→ 30 .

In First Square we have,

→ 3 - 4 - 2 - 3 = 19

→ (3)² + (4)² + (2)² + (3)²

→ 9 + 16 + 4 + 9

→ 38

→ 38 ÷ 2

→ 19 .

therefore, applying same logic in next ,

→ 3 - 1 - 2 - 6 = 19

→ (3)² + (1)² + (2)² + (6)²

→ 9 + 1 + 4 + 36

→ 50

→ 50 ÷ 2

→ 25 (Ans.)

Hence, 25 will replace the " ? ".
