To find the initial value of the sequence given points \((0, 8)\), \((1, 14.4)\), \((2, 25.92)\), and \((3, 46.656)\), we first note that the initial value refers to the value of the sequence when \(n = 0\).
From the provided points, at \(n = 0\), the value is \(8\). Thus, the initial value of the sequence is 8.
