Question

Find the next number.

2, 6, 30, 210, ?

The correct answer is

1890

Look at how each term grows from the previous one.

\(2 \times 3 = 6\), then \(6 \times 5 = 30\), then \(30 \times 7 = 210\).

The multipliers are the consecutive odd numbers 3, 5, 7, so the next multiplier is 9.

Multiply the last term: \(210 \times 9 = 1890\).

The multipliers are also successive prime numbers 3, 5, 7, and the next prime 11 would not match the odd-number pattern, so 9 is used.

Hence the next number is 1890.
