Answer:
0.5
Step-by-step explanation:
The given ordered pairs are: (1,2) (2,2.5) (3,3) (4,3.5) (5,4)
The corresponding sequence is :
2,2.5,3,3.5, 4,....
We can see that there is a common difference of d=0.5.
Better still we could use the slope formula:
[tex]m = \frac{y_2-y_1}{x_2-x_1} [/tex]
We substitute the point (1,2) and (2,2.5).
The rate of change of this sequence is:
[tex]m = \frac{2.5 - 2}{2 - 1} = \frac{0.5}{1} = 0.5[/tex]
