A piece of paper has an area of \( 256 cm ^ { 2 } \) . A strip is cut off that is \( \frac { 1 } { 4 } \) the original area. From that strip, another strip is cut off that is \( \frac { 1 } { 4 } \) the area of the first, and so on. Here is a graph and table representing sequence \( k \) , where \( k ( n ) \) is the area in square centimeters of the strip of paper after n cuts. (See question at the bottom in Blue.)
Write an \(n^{th} \)term equation to define sequence \( k ( n )\)
