(7 + 5)² = (12)² = 144
(3 + 4)² = (7)² = 49
(5 + 1)² = (6)² = 36
(2 + 8)² = (10)² = 100
(4)² + (6)² / 2 = 16 + 18 = 34
(9)² + (8)² / 2 = 81 + 32 = 113
(1)² + (4)² / 2 = 1 + 8 = 9
पहली पंक्ति ⇒ 33 = 8 × 2 + 17
दूसरी पंक्ति ⇒ 29 = 2 × 12 + 5
तीसरी पंक्ति ⇒ ? = 2 × 10 + 13 = 33
9 + 2² = 13
13 + 3² = 22
22 + 4² = 38
∴ लुप्त संख्या = 38
∴ 1³ − 1 = 0
2³ − 1 = 7
3³ − 1 = 26
4³ − 1 = 63
∴ लुप्त संख्या 63 होगी
3 = 1 × 2 + 1
105 = 7 × 14 + 7
117 = 9 × 12 + 9
8² = 64, 2² = 4, 5² = 25,
∴ 1² = 1
