The differences between consecutive revenues keep increasing, so a linear model does not fit the data exactly.
The ratios between consecutive revenues are constant, so an exponential model fits the data exactly.
The model R=6000(1.2)t fits the table, because the revenue grows by a factor of 1.2 starting from $6,000.
A line through the points for year 0 and year 4 would under-predict the revenue in year 2.
