Odd Man Out & Series
Important Instructions
Find out the wrong number in the series. 10, 26, 74, 218, 654, 1946, 5834
Answer: D
2nd term = (1st term) x 3 - 4 = 10 x 3 - 4 = 26.
3rd term = (2nd term) x 3 - 4 = 26 x 3 - 4 = 74.
4th term = (3th term) x 3 - 4 = 74 x 3 - 4 = 218.
5th term = (4th term) x 3 - 4 = 218 x 3 - 4 = 650.
5th term must be 650 instead of 654.
