AI explanation

We analyze the pattern by looking at the multipliers between consecutive terms. The multipliers are 1.5, 2, 2.5, 2.5, 4.2, and 4, which reveals an inconsistency. The intended pattern uses consecutive integer multipliers of 1.5, 2, 2.5, 3, 4, and 5, so multiplying 30 by 3 should give 90 instead of 75. Therefore, the wrong number is 75.
