Answer 2

Answer :

The Missing number of the series is 29.

Step by step explanation :

Hey Mate,

Given Number Series : 260, 216, 128, 108, 62, 54, X, 27

Solution : This is double series base question.

1st Series : 260, 128, 62, X

2nd Series : 216, 108, 54, 27

Solution of series one :

260/ 2 = 130 - 2 = 128

128/ 2 = 64 - 2 = 62

62/ 2 = 31 - 2 = 29

The Missing number of the series is 29.

Solution of series second :

216/ 2 = 108

108/ 2 = 54

54/ 2  = 27
