Find the range of all the multiples of 3 between 10 and 20

List the multiples of 3:

3, 6, 9, 12, 15, 18,21

The ones between 10 and 20 are:

12, 15, 18

The range is the difference between the highest and lowest numbers.

Range = 18 - 12 = 6

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.

i have done this all on a piece of paper but idk how to put it on here cuz it needs to be drawn
