D Correct answer
Explanation

The series follows alternating operations: +2 then ×2 repeated in groups of 3. Group 1: 3+2=5, 5×2=10 (should be 7). Group 2: 6+2=8 (but we have 10), 8×2=16 (but we have 14). Group 3: 12+2=14 (should be 24 based on pattern break). The number 24 breaks the established alternating pattern.
