If the product of the 4^(th), 5^(th) and 6^(th) terms of a geometric progression is 4096 and if the product of the 5^(th), 6^(th) and 7^(th) - terms of it is 32768, find the sum of first 8 terms of the geometric progression. For any two positive numbers, the three means AM, GM and HM are in geometric progression.
