The following dot plot represents two data sets, A and B. The mean of set B is about ( 30,40,50) higher than the means of set A, which is about(half, same as, twice) the mean absolute deviation of either set.

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.

yes yes yes yes yes yes yes yes yes

(x, y)→(x − 8, y − 7)
