Answer:
.45714285714
Step-by-step explanation:
multiply then divide
We use equations for geometric sequence. We do as follows:<span>
a(n) = a(1) r^(n-1)
20 = ar^(2-1)
</span>20 = ar<span>
a = 20/r
11.25= ar^(4-1)
</span>11.25 = ar^3
<span>11.25 = (20/r)r^3
r = 0.75
Hope this answers the question. Have a nice day.</span>
