Answer:
0.046875 aka 3/64
Explanation:
In a geometric sequence, each term will be related to the previous term by undergoing either multiplication or division.
In this case, each case is exactly 1/2 of the previous term. 12 is half of 24, and 6 is half of 12. By continuing this sequence, we get
1: 24
2: 12 (24 * 1/2)
3: 6 (12 * 1/2)
4: 3 (6 * 1/2)
5: 3/2 (3 * 1/2)
6: 3/4 (3/2 * 1/2)
7. 3/8 (3/4 * 1/2)
8. 3/16 (3/8 * 1/2)
9. 3/32 (3/16 * 1/2)
10. 3/64 (3/32 * 1/2)
