Manuela has a total of 40 DVDs of movie and television shows. The number of movies is 4 less than 3 times the number of television shows. Write and solve (by substitution) a system of equations to find the number of movies and television shows that she has on DVD

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.

i do not know this sorry : (

10 down (bang1)

5 up

5down (2)
