how to formulate this?

I have a row (e.g. b1:z1), this contains values that must be in a scenario
like these

(a) All values in the row to be the same, (e.g. 2,2,2,2,2,2,2,2,2,,,,2)
(b) Ascending order, (e.g. 1,1,1,2,2,2,2,2,3,3,3,3,3,3,3,3,,,5)
(c) Descending order. (e.g. 2,2,2,2,2,1,1,1,,,,1)

I need to place a formula on cell a1 to show something like this
1. if all values on same row scenario (a) ...the result will show "need
upgrade - not evaluated"
2. if values are in ascending order scenario (b)......the result will show
"upgraded - evaluated"
3. if the values in descednding order scenario (c)....the result will show
"no legal reference"

i hope i explain it clear for someone who may help me with this.

regards,
driller
