In a data series that appears one number after another, each number is the product of four and the square of the previous number. If the first number in the series is t, what's the third number that comes up after the appearance of t?

Function X(n)

X(1) = t
X(n) = 4 * (n-1)^2 (n>=2)

**********************************************

X(1) = t
X(2) = 4t^2
X(3) = 4 * (4t^2)^2 = 4^3 * t^4
X(4) = 4 * (4^3 * t^4)^2 = 4^7 * t^8

x(1) = t
x(2) = 4(t^2)
x(3) = 4(4t^2)^2 = 4^3 t ^4
x(4) = 4(4^3 t^4)^2 = 4(4^6 t^8) = (4^7)(t^8)
