Concept:Each term is obtained by multiplying the previous term by the next odd number (3, 5, 7, ...).Explanation:Start with 2. Multiply by 3 to get 6.Multiply 6 by 5 to get 30.Multiply 30 by 7 to get 210.The multipliers are consecutive odd numbers: 3, 5, 7. The next odd number is 9.So, multiply 210 by 9 to get 1890.
