Fill in the blank so that the equation is always true: 4x-4=4x+__ fill in the blank so that the equation is sometimes true: 4x-4=4x__

For the first one:

Insert a "-4".

For the second one:

Insert a "+4".

I do not think you would like to hear that explanation

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.
