Step-by-step explanation:
suppose the number is x
so
(x-8) * 2 =24
x-8=12
x=12+8
x=20
Answer:
-2 i think im not to suure
Step-by-step explanation:
Arithmetic sequence: must have a constant common difference.
3/20-1/10=(3-2)/20=1/20
5/30-3/20=(10-9)/60=1/60
Difference is not constant, so no.
Geometric sequence: must have a common ratio
30/20 / (1/10) = 15
5/30 / (3/20) = 100/90 = 10/9
ratio is not constant, so no.
The answer is (c) neither geometric nor arithmetic
