Joe takes 2 steps for every one step that Kim takes. Write an equation in two variables showing the relationship between Joe’s steps and Kim’s steps. If Kim takes 15 steps, how many steps will Joe have to take to cover the same distance?

table 1

step-by-step explanation:

1-16

2-32

4-64

8-128

all multiples of 16

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.
