Margie owns a small recycling company where she picks up empty glass bottles from restaurants. At the first restaurant, she picks up 50 bottles. At each restaurant after this, she picks up 4 more bottles than she picked up at the restaurant before. Assume that this pattern continues. a) How many bottles does she pick up at the 20th restaurant?

b) How many total bottles has she picked up after visiting 20 restaurants?

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.

answer: b.48 for

step-by-step explanation:

c.

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.
