Use the rule for term n of a linear growth or decay model
A construction site's mobile crane is bought for $13,761. Its value falls by $407 for every block of 1000 hours run
Let \(V_n\) be the value of the crane, in dollars, after \(n\) blocks of 1000 hours run
\[V_0 = \$13{,}761\]
\[V_{n+1} = V_n - \$407\]
