Alana's space shuttle crew accidentally left her behind on a mysterious planet. She soon realizes that her body is aging much faster on this planet than it did on Earth. Alana's body
ages 7 years for every week she spends on this strange planet.
There is a proportional relationship between the number of weeks Alana spends on the
planet, x, and the number of years she ages, y.

The proportion of number of weeks (x) to the number of years aged in that week (y) would be 1:7. I'm not very good at explaining things but I hope this helped...

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.
