Answer:
Concept :
A series of numbers that follow a pattern is referred to as a number series. Candidates must locate the incorrect or missing number in the given sequence. It consists of a series in which the previous term is added to or subtracted from the subsequent term by a fixed amount.
Explanation:
Given :
888, 454, 237, 128.5, 76.25, 47.125
To Find :
The wrong term
Solution :
(888/2) + 10 = 454 ,
(454/2) + 10 = 237,
(237/2) + 10 = 128.5,
(128.5/2) + 10 = 74.25,
(74.25/2) + 10 = 47.125
(76.25/2) + 10 = 48.125
∴ The value 48.125 is not in the question. So, the wrong term is 76.25.
