Correct Answer: (43 – 82)
Solution :
Let's check each option –
First option:
55 – 107→(55 × 2) – 3 = 110 – 3 = 107
Second option:
43 – 82→(43 × 2) – 3 = 86 – 3 = 83 ≠ 82
Third option:
64 – 125→(64 × 2) – 3 = 128 – 3 = 125
Fourth option:
39 – 75→(39 × 2) – 3 = 78 – 3 = 75
So, only the second option does not follow the same pattern as the other three options. Hence, the second option is correct.
