Answer:
5
Step-by-step explanation:
The nth term of a geometric series is:
a_n = a₁ (r)^(n-1)
where a₁ is the first term and r is the common ratio.
Here, we have:
40 = a₁ (r)^(4-1)
160 = a₁ (r)^(6-1)
40 = a₁ (r)^3
160 = a₁ (r)^5
If we divide the two equations:
4 = r^2
r = 2
Now substitute into either equation to find a₁:
40 = a₁ (2)^3
40 = 8 a₁
a₁ = 5
-4/5 is equal to -0.8
Hope this helps
Sorry if I'm wrong
Good luck!

f-12=2(b-12)
f=2+b
2+b-12=2(b-12)
b-10=2b-24
minus b both sides
-10=b-24
add24
14=b
14-12=2
2+2=4
