C Correct answer
Explanation

The pattern multiplies each term by consecutive odd numbers starting from 0.5: 4 × 0.5 = 2, 2 × 1.5 = 3, 3 × 2.5 = 7.5 (not 8), 7.5 × 3.5 = 26.25, 26.25 × 4.5 = 118.125. The number 8 breaks this pattern. To verify, 8 should have been 7.5 (3 × 2.5), which then correctly produces 26.25 when multiplied by 3.5.
