In order to solve this problem, We need to substitute the first four numbers (1,2,3,4) for n. After this we calculate:
First item:
a1= -2*1 + 4=-2+4=2
Second item:
a2= -2*2 + 4
=-4+4=0
Third item:
a3= -2*3 + 4
=-6+4=-2
Forth item:
a4= -2*4 + 4
=-8+4=-4
So the first 4 items are: 2,0,-2,-4..
27-4=23-4=19-5=14-4=10-5=5-5 ( 3 pizzas and 3 videos)
The missing segment is 25

Answer:
y = 10x - 5
Explanation:
The equation of the line has the general formula:
y = mx + c
where:
m is the slope = 10
c is the y-intercept = -5
Substitute with the givens in the above formula to get the equation as follows:
y = mx + c
y = 10x + (-5)
y = 10x - 5
Hope this helps :)
