Find the wrong number in the given series: 100, 240, 480, 1344, 4300.8, 15482.88, 61931.52
- 240
- 61931.52
- 15482.88
- 1344
Correct answer: 1344
Solution
The series is intended to follow a pattern of multiplying by increasing factors. If 100 is multiplied by 2.4, then by 2, then by 2.8, the next terms should continue consistently; 1344 breaks that pattern. Hence, 1344 is the wrong number.
