Match formula for multiple, different cells

Hi,
Can you match data from multiple cells that don't fall within an array? For example, I want to match figures from specific cells (A2, A4, A6, A8). And within that formula is there a way of making the value the next lowest number rather than a specific figure?

Many thanks

Single cell match

=MATCH(1,A2,0)

Array of cells match

=MATCH(1,A2:A8,0)

Specific cells match???

=MATCH(1,A2,A4,A6,A8,0) ????

why these cells:A2,A4,A6,A8?
if there is a condition, then =MATCH(1,if(conditioon,A2:A8),) as CSE

There's no direct way to do that.
With some manipulation probably, but need more information.

Example:
This will do it
=MATCH(4,CHOOSE({1,2,3,4},A2,A4,A6,A8),0)

However, Understand that it's NOT returning the row # relative to the cell
If say 4 was in A4, that formula will return 2 (A4 is the 2nd cell specified in the formula)

To make it return the next lower value, just subract 1
=MATCH(4,CHOOSE({1,2,3,4},A2,A4,A6,A8),0)-1



Now there's probably far better/easier ways to do what you're looking for.
As Tim suggested, is there some pattern or criteria that determines which cells to look at ? That could probably be used.
