ArithmeticNumber Series & Progressions
A number series is given with one wrong term. Identify the wrong term given: 53 59 63 67 71
- a.53
- b.63
- c.67
- d.71
Answer: (A) 53
The series should increase by +4 each time: 55→59→63→67→71. Each consecutive term increases by 4. The first term should be 55, not 53. Therefore, 53 is the wrong term.
