A Correct answer
AI explanation

The underlying pattern multiplies the difference between terms by 0.5 and adds it back to the previous term. For example, 6 minus 1.5 is 4.5, but using the exact pattern of x0.5 + 0.5 yields 4, 5.5, 10.25, and 22.75. The series continues with 5.5 multiplied by 2 plus 0.5 being 11.5, proving 22.5 is the incorrect term.
