Answer 1

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.
