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 91Related questions
