The local library lends an average of 68.24 books to readers each day. what is the average number of books lent to readers in a week?

The local library lends an  average books per day  = 68.24

We know there are 7 days in a week  

To find the the average number of books lent to readers in a week, we multiply the number of days in a week by average number of books per day.

let x be the  average number of books per week  

x=  68.24 * 7  

x= 477.68

The local library lends an average of 477.68 books to readers every week.

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.
