Understanding the Number Series
In the given number series: 1050, 420, 178, 67.2, 26.88, 10.752, we need to identify the incorrect number. Let's analyze the pattern.
Identifying the Pattern
1. From 1050 to 420:
- Calculation: 1050 ÷ 2.5 = 420
2. From 420 to 178:
- Calculation: 420 ÷ 2.36 = 178 (approximately)
3. From 178 to 67.2:
- Calculation: 178 ÷ 2.64 = 67.2 (approximately)
4. From 67.2 to 26.88:
- Calculation: 67.2 ÷ 2.5 = 26.88
5. From 26.88 to 10.752:
- Calculation: 26.88 ÷ 2.5 = 10.752
Identifying the Incorrect Number
The division factors are not consistent throughout the series:
- The transition from 420 to 178 uses a divisor of approximately 2.36, which deviates from the consistent pattern of dividing by either 2.5 or 2.64.
- The expected number after 420, following the pattern, should be around 168 (420 ÷ 2.5).
Conclusion
Hence, the number 178 does not fit the established pattern in the series, making it the incorrect number.
Thus, the correct answer is option B: 178.

1050 x (2/5) = 420
420 x (2/5) = 168
168 x (2/5) = 67.2
67.2 x (2/5) = 26.88
26.88 x (2/5) = 10.752
Hence, 178 is the wrong number in the given series
