Answer: To calculate the difference between consecutive values of x or y, you need to subtract the value of x or y at the previous point from the value of x or y at the current point.
For example, if you have a set of data with x and y values:
x y
1 3
2 5
3 8
4 11
5 15
To calculate the difference between consecutive values of y, you would subtract the y-value at the previous point from the y-value at the current point. For example, the difference between the y-values for the first two points is:
5 - 3 = 2
The difference between the y-values for the second and third points is:
8 - 5 = 3
You can continue this process to find the differences between all consecutive pairs of y-values.
Similarly, to calculate the difference between consecutive values of x, you would subtract the x-value at the previous point from the x-value at the current point. For example, the difference between the x-values for the first two points is:
2 - 1 = 1
The difference between the x-values for the second and third points is:
3 - 2 = 1
Again, you can continue this process to find the differences between all consecutive pairs of x-values.
