Solution:तर्क :- (पहली संख्या × 4 - 3) = दूसरी संख्या (दूसरी संख्या × 4 + 3) = तीसरी संख्यायहाँ, (18, 69, 279) → (18 × 4 - 3) = 69
(69 × 4 + 3) = 279
(12, 45, 183) → (12 × 4 - 3) = 45
(45 × 4 + 3) = 183
इसी प्रकार
(32, 125, 503) → (32 × 4 - 3) = 125
(125 × 4 + 3) = 503
(18, 69, 279):
18 × 4 - 3 = 72 - 3 = 69
69 × 4 + 3 = 276 + 3 = 279 ✓
(12, 45, 183):
12 × 4 - 3 = 48 - 3 = 45
45 × 4 + 3 = 180 + 3 = 183 ✓
(32, 125, 503):
32 × 4 - 3 = 128 - 3 = 125
125 × 4 + 3 = 500 + 3 = 503 ✓
