We are given the following data:
[tex]\begin{gathered} 100 \\ 110 \\ 121 \\ 133.10 \end{gathered}[/tex]
We notice that each value is approximately the previous value plus 10:
[tex]\begin{gathered} 100+10=110 \\ 110+10=120\approx121 \\ 121+10=131\approx133.10 \end{gathered}[/tex]
Therefore, we can use a linear expression to approximate the behavior of the data set.
