first mechanic: $_ per hour
Second mechanic: $_per hour

sorry, i don't know i just need points, i'm new here. chao

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.

5   1/4   miles per hour

step-by-step explanation:

15   3/4 / 3 = 5   1/4
