Question

List the elements of the following sets
where P = {1,2,3...}

A={x:x € P, 3 < x < 12}
B={x:x € P, x is even, x < 15}
C={x:x € P, 4 + x € 3}
D={x:x € P, x is multiple of 5}

Answer 1

x∈P means x stands for a positive integer.
since x∈A means 3<x<12,
A={4,5,6,7,8,9,10,11}

You can do B,C, and D similarly.

True
