MATCH reverse order

In an excel sheet, I have from A1 to A6:

1, 2, 4, 6, 8, 9

I would like, using MATCH function, to retrieve the smallest interval that contains 5. Here, 4 and 6.

I can easily use the MATCH and INDEX function to find 4, but I can't find a way to find the 6.

How can I reverse the order of the Array in the MATCH function?
