One number is wrong in the following number series given in each of the following questions. You have to identity that number and assuming that a new series starts with that number following the same logic as in the given series, what will be the third number in the new series?
214 18 162 62 143 90 106
Correct Answer: Option D
The pattern of given series is:
→ 214,
→ 18 = 214 – (14)2,
→ 162 = 18 + (12)2,
→ 62 = 162 – (10)2,
→ 143 ≠ 62 + (8)2 = 126,
→ 90 = 126 – (6)2,
→ 106 = 90 + (4)2,
∴ 143 is the wrong number in the series and the correct number will be 126
Based on the above pattern we can create the following series
→ 143,
→ -53 = 143 – (14)2,
→ 91 = (-53) + (12)2,
Hence, third number in the new series is 91
