Answer:
38 is the wrong number.
Explanation:
Gap between 3 and 10 is 7,
Gap between 10 and 18 is 8,
Gap between 18 and 27 is 9,
Gap between 27 and 38 is 11,
Gap between 38 and 57 is 19,
Gap between 57 and 69 is 12.
If Gap difference is 10 instead of 11,
then gap difference is 11 instead of 19
and last one is correct
so wrong number is 38.
