Answer:
10. Arithmetic (-6)
11. neither, it seems to go in a pattern of /2 but the 1 doesn't fit.
12. Geometric (divide by 3)
13. Neither, because it is two different sequences intertwined.
14. 1, 1/4, 1/16 (divide by 4)
15. -432, 2,592, -15,552(multiply by -6)
Step-by-step explanation:
Arithmetic means adding and subtracting. (a constant)
Geometric means multiplying and dividing. (a constant)
If the sequence increases by adding or decreases by subtracting it's Arithmetic.
If the sequence increases by multiplying or decreases by dividing it's geometric.
