Given the graph and different lines passing through it, we were asked to find the common difference of the sequence.
Using common the slope formular to find the common difference.
y2 - y1/x2 - x1
So lets take two two points of the line
(1, 4) and (4, 3)
Where:
x1 = 1
y1 = 4
x2 = 4
y2 = 3
Therefore, the common difference is:
= 3 - 4
4 - 1
= -1/3
Therefore, the common difference is -1/3
So the correct option is the the second option which is -1/3
