Question
Given below is a number series. One term of the series
is denoted by X. You have to calculate the value of X and by using the value, you have to replace the question mark (?): If 7 5 20 52.5 160.5 Then, (X + 1) ( X – 1) = ?Solution
7 `xx` 0.5 + 0.5 = 4 4`xx` 1 + 1 = 5 5 `xx` 1.5 + 1.5 = 9 9 `xx` 2 + 2 = 20 20`xx` 2.5 + 2.5 = 52.5 52.5 `xx` 3 + 3 = 160.5 x = 9 (9-1) (9+1) =`10xx8` = 80
