2x-4=49
2x=54
x is equal to 27
An=a1r^(n-1)
given
a5=1/24
a10=1/768
we know that
a5=1/24=a1r^(5-1) and
a10=1/768=a1r^(10-1)
so
1/24=a1r^4
1/768=a1r^9
(a1r^9)/(a1r^4)=r^5=(1/768)/(1/24)=1/32
r^5=1/32
take 5th root of both sides
r=1/2
we have
a5=a1r^4=1/24
evaluate r^4 or (1/2)^4
1/16
a1(1/16)=1/24
times both sides by 16/1
a1=16/24
a1=2/3
the first term is 2/3
Answer:
Brandon
Step-by-step explanation:
GIVEN: Branden and Pete each play running back. Branden carries the ball
times for
yards, and Pete has
carries for
yards.
TO FIND: Who runs farther per carry.
SOLUTION:
Total yards traveled by Brandon 
No. of times ball carried by Brandon 
Average yards per carry for Brandon 



Total yards traveled by Pete 
No. of times ball carried by Pete 
Average yards per carry for Pete 

≅ 
As the number of yards per carry is higher for Brandon , therefore he runs farther per carry.
