Answer:
21, 22 and 23
Step-by-step explanation:
Given the set A = {x | x ∈ N and 20 < x}
, from the set it can be seen that the element of the set are natural numbers where 20< x.
If 20< x
reciprocating both sides will change the sense of the inequality
1/20>1/x
cross multiply
x > 20
This means that the values of x are values grater than 20.
The smallest three values will be the smallest three natural numbers greater than 20 and they are 21, 22 and 23. Note that natural numbers are whole numbers.
