Answer:
2, 0, -2, -4
Step-by-step explanation:
an = 4 − 2n

the money given by joe to hector is 125$
let the hector works for x weeks,
it is given that hector earns 50$ in a week,
so the total money hector wants to save is 1100$
now
![1100=50x+125](https://tex.z-dn.net/?f=1100%3D50x%2B125)
from the above inequality, we will find x
![\begin{gathered} 1100-125=50x \\ 50x=975 \\ x=19.5 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%201100-125%3D50x%20%5C%5C%2050x%3D975%20%5C%5C%20x%3D19.5%20%5Cend%7Bgathered%7D)
it means the hector will work for 20 weeks in order to earn 1100$.
