What is the next number in the series? 10, 30, 90, ___
270
Compare each term with the one before it: \(30 \div 10 = 3\) and \(90 \div 30 = 3\).
So each term is the previous term multiplied by 3 (a geometric progression with common ratio 3).
The next term is \(90 \times 3 = 270\).
Hence, the answer is 270.
