<PRE><B>Question 1024765</B>
Given the geometric sequence: 33,121,4811...
---
Note:: Your posted sequence is not geometric:: 131/33 = 11/3
but 4811/121 is not 11/3
-------------------------------
Assuming 33,131 are the correct first-two terms, 
r = 121/33 = 3 2/3 or (11/3)
a(1) = 33
----------------------
Find an explicit formula for an. 
a(n) = 33*(11/3)^n
-----------------------------
Find a(10) = 33*(11/3)^10 = a very large number
=================================== 

2. The purchase value of an office computer is 12690 dollars. Its annual depreciation is 1896 dollars. 
The value of the computer after 6 years is dollars.
V(t) = 12690-1896t 
V(6) = $1314
