I need more explanation on question number 1. How do we arrive at 2 and 5

Square both upper and lower number individually and add the result to get the number for the next card written from top to bottom.

I need explanation on question number 2.

Rajesh Kumar said...

For the 2nd #brainteaser the logical reasoning used is as below
The next number in the sequence represents the number of letter in the previous number when that number is written in English e.g.
ONE-> Three letter and so the next number is 3.
Thus the sequence is ONE THREE FIVE FOUR FOUR and so on.

need explanation on question number 3

Rajesh Kumar said...

Logical reasoning is explained as below for question number 3.
The number in the center of the Circle is the Multiplication of the Absolute Differences between the outer horizontal and vertical numbers.
So in the last case the central number is (9-1) * (2-1) = 16.
Please let me know if this logical reasoning is not clear for this question?
