A Correct answer
Explanation

The pattern should be: subtract consecutive even numbers in decreasing order: 462-40=422, 422-42=380, 380-38=342, 342-36=306. However, 422 breaks the pattern as it should be 462-40=422, but the next subtraction should be 422-38=384, not 380. Therefore, 422 is the wrong number.
