What IS
the scale factor of this dilation?

3

Step-by-step explanation:

out of 2 we need to create 2+4=6

and out of 3 we need to create 3+6=9.

2×f = 6

f = 6/2 = 3

and it fits also in the other relation

3×f = 3×3 = 9

perfect.

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.
