D Correct answer
Explanation

The pattern is: multiply the previous number by 2, then subtract 2, 4, 6, 8, 10 alternatively. Let's check: 6 × 2 - 2 = 10, 10 × 2 - 6 = 14, 14 × 2 - 2 = 26 (not 34), 26 × 2 - 6 = 46 (not 66). The actual pattern seems to be: 6, 10, 18, 34, 66, 130 where each step is ×2 - 2. The given 14 breaks this pattern, making it the wrong number.
