Answer:
a(14)=469762048
Step-by-step explanation:
geometric sequence= a(n)=a*r^(n-1)
we have:
a=7
r=28/7=4
So:
a(14)=7*4^(14-1)
=7*4^(13)
=469762048
hope this helps
Answer:
x=4-3y
Step-by-step explanation:
Answer:

Step-by-step explanation:

Cross multiply,
y(x - 8) = x +3
yx - 8y = x + 3
yx - 8y -x = 3
yx - x = 3 + 8y
(y - 1)x = 3 +8y

Answer:
to solve this you need to find out what number n is to make it equal 28.
Step-by-step explanation:
19+3 =22 so 3 is not it
19+9=28
answer is 9
hopefully this is right and this gets to you on time
