The logic followed is:- Second number = First number × 4 + 3 Third number = Second number × 3 + 6 The given set is (12, 51, 159) Second number = First number × 4 + 3 = 12 × 4 + 3 = 48 + 3 = 51 Third number = Second number × 3 + 6 = 51 × 3 + 6 = 153 + 6 = 159 Checking the options:- 1) (8, 35, 111) Second number = First number × 4 + 3 = 8 × 4 + 3 = 32 + 3 = 35 Third number = Second number × 3 + 6 = 35 × 3 + 6 = 105 + 6 = 111 Hence, the correct answer is "(8, 35, 111)".
