Answer:
$0.65
Step-by-step explanation:
2.40-1.10=1.3
1.3/2=.65
The points are (-4,2) and (3,-4)
using y2-y1/x2-x1
-4-2/3-2
-6/1
slope (m) is -6
to find b part of equation (y=mx+b) plug in point value for x and y
2=-6(-4)+b (multiply -6 and -4)
2=24+b (subtract 24 over)
b=-22
final equation is y=-6x-22
The only formula that can be used to describe the sequence is definitely the third one

. So count like that

and so on. You can check others by yourself to check if I'm right or not.
