Find the fifth term of a sequence whose first term is 8 and common ratio is 3/2
1 answer:
Answer:
Option c. 81/2
Step-by-step explanation:
Fifth term: a5=?
First term: a1=8
Common ratio: r=3/2
an=a1*r^(n-1)
with n=5
a5=a1*r^(5-1)
a5=a1*r^4
Replacing the known values:
a5=8*(3/2)^4
a5=8*(3)^4/(2)^4
a5=8*81/16
Simplifying: Dividing the numerator and denominator by 8:
a5=(8*81/8)/(16/8)
a5=81/2
Answer: Option c. 81/2

We can divide the amount he traveled (640) by the time he traveled (10):
640 / 10 = 64.
So Curtis drove 64 miles per hour.
Check:
64 miles per hour multiplied by 10 hours:
64 * 10 = 640
