I don't understand what the question is asking first of all.

The answer is 4.

Help is much appreciated.

**Steve**, Tuesday, November 29, 2011 at 12:00amA geometric sequence cannot start with 0, or all the terms will just stay 0.

So, you want n such that each term is a constant multiple of the one before.

(8+n)/(0+n) = (32+n)/(8+n)

(8+n)^2 = n(32+n)

64 + 16n + n^2 = 32n + n^2

64 = 16n

n=4

So, the sequence starts out 4,12,36,... with each term 3x the previous one.
