Correct option is B
Given: 5, 10, 17, 28, 42, 58, 77
Logic is adding of 5, 7, 11, 13, 17 and 19 prime number
Add 5 (prime) → 5 + 5 = 10
Add 7 (prime) → 10 + 7 = 17
Add 11 (prime) → 17 + 11 = 28
Add 13 (prime) → 41
28+13=41 (Expected, but the series has 42)
Add 17 (prime) → 41 + 17 = 58
Add 19 (prime) → 58 + 19 = 77
The number 42 does not fit the logic because the expected value at that step should be 41. Hence, 42 is the incorrect number in the series.
