Easy question: The width of an instruction book is 0.3 m. The length of a shelf is 145 metres. What is the maximum number of practise books that can be stored on the shelf? Your answer must be rounded to the nearest whole number.

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.

c

-by-step explanation:

it would be c

hope this !
