1. b, 2.c, 3.b

Step-by-step explanation:

for 1, b is the nonproportional one because it has a +5 at the end, for 2, c is the proportional one because thats the only one that has a constant relationship of x2, in number 3, the non proportional one is b because there is an added cost and it does't have a constant relationship.

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.
