Explanation

The series is 4665600, 129600, 5184, 324, y, x. Dividing: 4665600/129600 = 36, 129600/5184 = 25, 5184/324 = 16. The divisors are 6^2, 5^2, 4^2. Next divisors should be 3^2=9 and 2^2=4. y = 324/9 = 36. x = 36/4 = 9. Sum = 36+9 = 45. z = 45 * 1.5 = 67.5. First term / z = 4665600 / 67.5 = 69120.
