Answer:
I believe the answer is 0.7813
Step-by-step explanation:
Find the difference between 400 and 200, as they are first and second terms. This is going to be 0.5 since it is being divided.
The formula is: a∨n=a∨1(r)^(n-1)
n= the number of the sequence you are looking for
r=0.5
a∨1=400
a∨2=200
400(0.5)^(10-1)
