Please help it’s due in 20 minutes and it’s easy i just don’t get it :( i’ll mark as brainiest !!

d is 18, a is 11, c is 9 and b is 12

Step-by-step explanation:

i think its this, although im only really sure for d.

im 50 percent sure with the others as they add to 50

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.

because they could drop even lower..
