Answer:
[tex]C = \{0,7,14,21,28\}[/tex]
Step-by-step explanation:
Given
[tex]C \{7n: n < 5\}[/tex]
Required
List the elements
Assume that n is not negative, the values of n are:
[tex]n = \{0,1,2,3,4\}[/tex]
So, the values of C is:
[tex]C = 7 * n[/tex]
[tex]C = 7 * \{0,1,2,3,4\}[/tex]
Multiply each set element by 7
[tex]C = \{7 *0,7 *1,7 *2,7 *3,7 *4\}[/tex]
[tex]C = \{0,7,14,21,28\}[/tex]
