E Correct answer
Explanation

The correct answer is E. The pattern is: 4 × 1 + 2.5 = 6.5, 6.5 × 2 + 1 = 14, 14 × 2.5 + 0.5 = 35.5 (should be 35.5, but 35.5 × 3 = 106.5, not 111.5). Actually the pattern increments by 0.5 in multiplier and decreases by 0.5 in addition. 35.5 is correct in sequence but 111.5 should be 106.5, making 35.5 the wrong number that breaks the pattern.
