Question


In the following question, if one term in the number series is wrong, find out the wrong term.

1, 3, 12, 25, 48


A. 25
B. 48
C. 1
D. 3


Answer: A. 25


Solution:

The term of the series is

(12-02) = 1,

(22-12) = 3,

(42-22) = 12,

(62-32) = 27,

(82-42) = 48.


So, 25 is wrong and Must be replaced by (62-32)= 27.
