Answer:
Step-by-step explanation:1
<span>The first two terms of a geometric sequence are a1=1/3 and a2=1/6. what is a8 the 8th term?
r=(1/6)/(1/3) = 1/2
a(8)= ar^7 = (1/3)(1/2)^7 = 1/3*1/128= 1/384</span>
Set up the proportion, you get 20/30=x/150. You will need to be 100 dollars.
(24·z^3)^2/(27·12·z) = (2^3·3·z^3)^2/(3^3·2^2·3·z) = (2^6·3^2·z^6)/(3^3·2^2·3·z) = 2^4·3^(-2)·z^5
a = 4 ; b = -2 ; c = 5
Its -1/2 because they are 9/4 then 7/4 then 5/4 then 3/4 and thats -2/4 which is equal to -1/2
