Hi! i chose 1/4. if anyone could check my work that'd be awesome!
if the center of dilation is at the origin, by what scale factor was octagon abcdefgh dilated?

one half (1/2)
one quarter (1/4)
2
4

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.
