General Term Given Points on a Graph

When graphing a sequence, the horizontal axis is used to represent the place in the sequence (n), the vertical axis is used to represent the value of the terms (u_n).

For example, if the points (3,16) and (7,52) were plotted on the graph of an arithmetic sequence, we could conclude:

    \begin{align*} u_3&=16\\ u_7&=52 \end{align}

We could then proceed as instructed here.
