On a set of steps, the first step from the base of the steps is labeled 1 , the second is labeled 2, and so on. Each step has the same height. The table below shows the step number and step's height from the base of the steps.\begin{tabular}{cc} Step number & Height from the base (meters) \\\hline 50 & 10 \\90 & 18 \\110 & 22\end{tabular}Write an equation to describe the relationship between n, the step number, and h, the height from the base.□
