Question

the population of Canada as estimated every 5 years since 1960, is shown in the table. 1.calculate the finite difference for the data set

Answer 1

The table for the finite difference for the data is shown below

From the table, the finite difference is calculated as

`\begin{gathered} f_2-f_1 \\ e.g\text{ =19.68 - 17.91 = 1.77} \end{gathered}`

That is the lower y-value minus the upper y-value, then you continue as follows.
