Let's see what your idea of the *last* number is:

A1.....B1.....C1.....D1
..........10......22..........

Which do you consider to be the *last* number?

The formula I suggested will return 22 as the last number.

Is it possible for it to look from right to left for the last numeric
value?

Try this:

=LOOKUP(1E100,1:1)

That will return the *last numeric value* from left to right in row 1,
A1:IV1.

The math is simply the difference between the values in two cells, but
one
of
the cells will change each time the table is updated.

For example, Row 1 headers are Apr, Mar, Feb, Jan, etc. and the last
column
is Prior Year. In At any given time, I want the value for the most
recent
month minus the prior year. How do I get it to automatically pick up
the
last non-blank cell in the row?

Thanks
