What is the range?
8, 10, 60, 3, 5, 13, 12, 40, 8

57

Step-by-step explanation: Range is the highest number of your set subtracted by the lowest number. So 60 minus 3 is 57.

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.
