Correct Answer: 20
Solution : Given: Row 1: 6, 4, 26 Row 2: 3, 7, 29 Row 3: 2, 6, ?
Divide the sum of the square of the first two numbers by 2 to get the third number – In row 1: (62 + 42) ÷ 2 = (36 + 16) ÷ 2 = 52 ÷ 2 = 26 In row 2: (32 + 72) ÷ 2 = (9 + 49) ÷ 2 = 58 ÷ 2 = 29 Similarly, follow the same pattern in row 3: (22 + 62) ÷ 2 = (4 + 36) ÷ 2 = 40 ÷ 2 = 20
So, the required missing number is 20. Hence, the first option is correct.
