Question

Which of the sets shown includes the elements of set Z that are both odd numbers and multiples of 7?

Z={-21, -14, -7.0, 7, 14, 21}
A {-21, 21)
B. {-21.-7. 7. 21)
C: {-14, 0.14)
D. {-21, -14, -7)

Answer 1

B. {-21.-7. 7. 21)

The set made up of odd numbers and multiples of 7 is given as;
