Help me, please e

Step-by-step explanation:

X going to the positive direction from 0 or bigger than 0 to

x = 0.5

2(0.5) - 1 = 0 = 0

x = 1

2(1) - 1 = 1 > 0

x = 2

2(2) -2 = 2 > 0

and so on...

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.
