Solution : Given:
102, 101, 98, 93, 86, 74, 66, 53
Let's find the difference between the numbers →

93 – 86 = 7
86 – 74 = 12
74 – 66 = 8
66 – 53 = 13
53 – 38 = 15
Here, the difference between the numbers is 2 and all are in sequence of odd numbers except the third option i.e. 74 .
So, 74 is the wrong number in the given sequence.
Hence, the third option is correct.
