Find the missing number in the following number series: 72, 36, 54, 135, ?
- 475.5
- 482.2
- 472.5
- 455.5
Correct answer: 472.5
Solution
The pattern is: \(72 \div 2 = 36\), \(36 \times 1.5 = 54\), \(54 \times 2.5 = 135\). Continuing the same style, the next multiplier is \(3.5\), so \(135 \times 3.5 = 472.5\).
