Correct Answer: (47 – 43 – 37)
Solution :
Let's check each option –
First option:
(57 – 53 – 49); 57 – 4 = 53 and 53 – 4 = 49
Second option:
(60 – 56 – 52); 60 – 4 = 56 and 56 – 4 = 52
Third option:
(50 – 46 – 42); 50 – 4 = 46 and 46 – 4 = 42
Fourth option:
(47 – 43 – 37); 47 – 4 = 43 and 43 – 4 = 39 ≠ 37
So, only the fourth option doesn't follow the same pattern as followed by the given set of numbers. Hence, the fourth option is correct.
