Here, 26 – 10 = 16
74 – 26 = 48 (16 × 3)
218 – 74 = 144 (48 × 3)
654 – 218 = 436 (144 × 3 = 432)
Wrong number is 654 as difference should be 432 and number should be 650.
⇒ 1946 – 650 = 1296 (432 × 3 = 1296)
Hence, the wrong number is 654.
74 – 26 = 48 (16 × 3)

654 – 218 = 436 (144 × 3 = 432)
Wrong number is 654 as difference should be 432 and number should be 650.
⇒ 1946 – 650 = 1296 (432 × 3 = 1296)
Hence, the wrong number is 654.
