Answer:
1. $30
2. $47.50
3. $7.20
Step-by-step explanation:
1. ( 30 + 45 + 15 ) / 3 = 30
2. ( 18 + 93 + 34 + 45 ) / 4 = 47.50
3. ( 9 + 4 + 5 + 8 + 10 ) = 7.20
Hello,
The question is
<span>"What are the explicit equation and domain for a geometric sequence with a first term of 2 and a second term of −8?"
It is a geometric sequence =>U(2)=U(1)*r==>-8=2*r ==>r=-4
U(1)=2=2*(-4)^0
U(2)=-8=2*(-4)=2*(-4)^1
U(3)=32=-8*(-4)=2*(-4)(-4)=2*(-4)^2
U(4)=-128=32*(-4)=2*(-4)^3
...
U(n)=2*(-4)^(n-1) where n>=1.
Answer C

Your answer is -2,146 because you have to try to get x by itself. So to do that you must subtract 2,318 and 18 from 190 to get your answer.
