AI explanation

The series follows a pattern where each term is multiplied by consecutive odd numbers to get the next term, verified by 30×7=210 and 1890×11=20790. Working backwards from 6, the missing term is 6 divided by 3, which equals 2. The problem states that Z is 250% more than this missing term, meaning Z equals 2 plus 250% of 2 (2.5 × 2), which totals 7.
