B Correct answer
Explanation

The pattern is: previous number × 1.5 + 6.5. Verifying: 3.5 × 1.5 + 6.5 = 11.75 (should be 12.5), but actually the pattern is n + 1.5, n + 3, n + 4.5, n + 6, n + 7.5 where increments increase by 1.5 each time. 3.5 + 8 = 11.5, 11.5 + 17 = 28.5... The correct pattern analysis shows 12.5 is wrong.
