Question
100, 164, 740, 3044, 9444,
20320 Find the wrong number in the given number series.Solution
ATQ, The series follows the pattern: 100 + (22 × 42 ) = 164, 164 + (42 × 62 ) = 740, 740 + (62 × 82 ) = 3044, 3044 + (82 × 102 ) = 9444, 9444 + (102 × 122 ) = 23844
I. 3x2 = 2x2 + 9x – 20
II. 3y2 = 75
I. 2x2 - 9 x + 9 = 0
II. 2y2 - 7 y + 3 = 0
I. 2x² + 11 x + 15 = 0
II. 2y² - 19 y + 44 = 0
I. 2x² - 9x + 10 = 0
II. 3y² + 11y + 6 = 0
I. 2y2 - 15y + 18 = 0
II. 2x2 + 9x - 18 = 0
I. 144x² - 163x - 65 = 0
II. 91y² - 128y -48 = 0
I. 2b2 + 31b + 99 = 0
II. 4a2 + 8a - 45 = 0
I. x2 - 9x - 52 = 0
II. y2 - 16y + 63 = 0
I. 104x² + 9x - 35 = 0
II. 72y² - 85y + 25 = 0
(i) 2x² + 14x - 16 = 0
(ii) y² – y – 12 = 0
