Data trend without a graph

[thomasson1]

I am attempting to trend data without using a graph. The data would look something like this:

Week	Revenue
1	$90,934.15
2	$143,314.75
3	$134,522.00
4	$202,343.00
5	$177,218.00
6	$132,985.75
7	$113,291.00
8	$62,821.00
9	$151,983.00
10	$161,214.80
11	$142,278.45
12	$85,135.00
13​	$150,590.00

I would simply want an arrow or something like "UP", or "Down" to display under the revenue column. Any guidance would be great.
