Answer:
It is a geometric sequence en the common ratio is: 
.
Step-by-step explanation:
1. By definition, a geometric sequence is a sequence in which you obtain a term by multiplying the previous one by a common ratio.
2. The common ratio is obtained by dividing a term by its preceding term.
3. Keeping this on mind, you have:
4. As you can see, the common ratio is 
Let the time Larry spend reading be x and the time he spend watching TV be y. Then
x + y ≤ 4 . . . (1)
x ≥ y . . . (2)
The
graph represents two straight lines with one line passing through
points (0, 4) and (4, 0) and the other one passing through points (0, 0)
and (2, 2). The two lines intersects at point (2, 2) with the portion
of the graph bounded by the x-axis shaded.
