Exercise 3 (Using Numbers)
It has to do with arithmetic progressions.
This exercise follows numerical order (1,2,3,...)
3+(1)=4
4+(2)=6
6+(3)=?

The answer is "c".
Exercise 4 (With Numbers-Two Variables)
This exercise can be analyzed in two ways:
First, the even numbers are in the increasing order interspersed with the odd ones, in the increasing order too.
Second Analysis:
2(+3)=5
5(-1)=4
4(+3)=7
7(-1)=?

The sequence adds 3 and subtracts 1 (+3-1)
We conclude the answer is "a".
Exercise 5 (With Tokens of Domino)
Observe the left half of each domino and then its right half.
Both, the left and the right halves of the domino increase in number
(0-1-2-3 / 1-2-3-4)
and each domino begins with the same number of dots as the former one's second half.
Thus, the answer is letter "c".
