Dividing the last in a series

J

Hi all, I have a spreadsheet like this:
3000
4000
5000
6000

I want to divide the last number by 3000, and only the last number. If I
add another number on after the last one, say 7000, I want to divide that
one, and only that one. Is there a way to do that?
Thanks!

Is the data always in ascending sequence so you divide the maximum by the
minimum?

=max(A1:A10)/min(A1:A10)

No, the data isn't always in ascending sequence.

For some reason my earlier post didn't show up, no, the data isn't always in
ascending order.

One way is to define your data as a dynamic range e.g. List

Insert=>Name=>Define

Enter "List" as name (for example)

In the Refers To box, enter an Offset formula that defines the range size,
based on the number of items in the column, e.g.:
=OFFSET(Sheet1!$A$2,0,0,COUNTA(Sheet1!$A:$A),1)
In this example, the list is on Sheet1, starting in cell A2

For your calculation put this in the required cell:

=OFFSET(A2,ROWS(List)-1,0)/(A2)

This divides last number in range "List" by first

An alternative:

=INDEX(A:A,MATCH(9.99999999999999E+307,A:A))/A2

The INDEX will find the last value.

I saw this in a just posted query.

=LOOKUP(2,1/(range<>""),range)

....added the /3000

=LOOKUP(2,1/(range<>""),range)/3000
