331 = 3 × 1 = 3
263 = 2 × 3 = 6
373 = 3 × 3 = 9
482 = 4 × 2 = 8

(2)³ = 2 × 2 × 2 = 8
(3)³ = 3 × 3 × 3 = 27
(4)³ = 4 × 4 × 4 = 64
(5)³ = 5 × 5 × 5 = 125
(6)³ = 6 × 6 × 6 = 216
(7)³ = 7 × 7 × 7 = 343
गलत संख्या = 124

380, 188, 92, 48, 20, 8, 2
= 73 - 61 = 12
तथा 42 - 29 = 13
अभीष्ट संख्याओं का जोड़ा = 42, 29
9, 19, 37, 75, 149, 297
(9 × 2) + 1 = 18 + 1 = 19
(19 × 2) - 1 = 38 - 1 = 37
(37 × 2) + 1 = 74 + 1 = 75
(75 × 2) - 1 = 150 - 1 = 149
(149 × 2) + 1 = 298 + 1 = 299
अतः 297 गलत है; इसके स्थान पर 299 होना होगा।
