The cost to mail a package is $0.44 for the first ounce, then $0.17 each additional ounce. Write a formula to represent this sequence. What is the cost to mail a 7-oz package?

Y=.44+.17x

Step-by-step explanation:

it would cost 1.46

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.
