In a science experiment a student concluded that a ray has to travel a distance from one corner at the top of the
rectangular prism to the opposite side where the surface
touching the floor is intersected. If the length, width, and
height of the prism are given as 24 inches and 8 inches, 6
inches respectively, what is the distance travelled by the ray?

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.
