Correct Answer - Option 1 : (2, 10, 1)
(Square of first number + square of third number) × 2 = Middle Number
(3, 68, 5) → ( 32 + 52) × 2= (9 + 25) × 2 = 34 × 2 = 68
1) (2, 10, 1) → ( 22 + 12) × 2= (4 + 1) × 2 = 5 × 2 = 1
2) (2, 72, 10) → ( 22 + 102) × 2= (4 + 100) × 2 = 104 × 2 = 208 ≠ 72
3) (5, 72, 8) → ( 52 + 182) × 2= (64 + 25) × 2 = 89 × 2 = 178 ≠ 72
4) (4, 64, 5) → ( 42 + 52) × 2= (16 + 25) × 2 = 41 × 2 = 82 ≠ 64
Hence, “(2, 10, 1)” is the correct answer.
