Identify the natural numbers x such that 2 < x ≤ 8 , which are 3, 4, 5, 6, 7, and 8.
Calculate x + 3 for each identified x .
List the results to define the set A by extension.
The set A by extension is { 6 , 7 , 8 , 9 , 10 , 11 } .
Explanation
Understanding the Set A We are given the set $A = {x+3 / x \in N, 2
