Directions (75-77): There is a wrong number in these series. Find the wrong number & pattern of the given series and answer the questions given below. Series A: 24, 31.5, 46.5, 69, 98, 136.5, 181.5 Series B: 5926, 886, 166, 46, 22, 18, 14 Series C: 11, 18, 44, 107, 231, 445, 788 Q75. X, Y & Z are the wrong number of the series A, B & C respectively. Find the relation between X, Y & Z. (a) X > Y < Z (b) X > Y > Z (c) X ≤ Y < Z (d) X > Y ≥ Z (e) X = Y < Z

1. X > Y < Z
2. X > Y > Z
3. X ≤ Y < Z
4. X > Y ≥ Z

Correct answer: X > Y < Z

Solution

In series A, the differences should increase by 7.5 each time, so 98 should actually be 99, making X = 98. In series B, the pattern leads to 22 being the wrong term, and in series C the wrong term is 445, so X is greater than Y but less than Z.
