Answer:

About 21.02

Step-by-step explanation:

divide 24.50 by 3 to find out what 1 poster costs

divide that from 171.50 to get 21.0171568627

figure out that basically nobody will accept anything smaller than a penny

round to the nearest hundredth

get 21.02

maybe I'm wrong

What is the arithmetic rule to the sequence: 1/3,4/3,7/3 find: f(10)

makkiz [27]

The the value of f(n)= $\frac{28}{3}$

Step-by-step explanation:

The Arithemetic sequence is given as a,a+d,a+2d......a(n-1)d

and f(n)=a(n-1)d

The given sequence is 1/3,4/3,7/3...

By comapring with Arithemetic sequence,

we get a=1/3

a+d=4/3

1/3 + d = 4/3

d=1

To find value of f(10):

take n=10

f(n)= $\frac{1}{3} +(10-1)1$

f(n)= $\frac{1}{3} +(9)1$

f(n)= $\frac{1+27}{3}$

f(n)= $\frac{28}{3}$
