I have the following data:

Code:
    100 	Feb. 4, 2000
    200 	Aug. 31, 2000
    300 	Mar. 25, 2001
    400 	Feb. 26, 2002
    500 	Aug. 14, 2002
    600 	Apr. 29, 2003
    700 	Dec. 2, 2003
    800 	Jun. 11, 2004
    900 	Jan. 15, 2005
Column 1 is "discovery number" and Column 2 is the date on which that discovery was made. So, discovery #200 was made on August 31, 2000.

What I want to do is figure out when Discovery #1000 will be made.

How would you go about this?
