Question 1142545: A Geometric progression X has a first term of 4a and its sixth term is 256. Another Geometric progression Y has a first term of 3a and its fifth term is 48.
i) First term of X
ii) Sum of the first four terms of X .

As posted, the problem makes no sense.
(1) The questions that are asked concern only sequence X, so the given information about sequence Y is irrelevant.
(2) Then, given only sequence X with first term 4a and sixth term 256, there is not enough information to determine a single solution. There are an infinite number of geometric sequences with first term 4a and sixth term 256.
Either the problem is flawed, or you have left out some required information in your presentation of the problem.
