I have a directory where there are subdirectories which have numbers as directories. For example I have a parent directory test now I have some subdirectories like 1,2,3,4,5,6,7. Now I have a local exported variable like export a=3. I want to delete directories that are above or equal to $a and below or equal to $a+3, So I want to delete files 4,5. How can I achieve this in Ubuntu 18.04.6 LTS.

I tried rm -rf {$a..$($a+3)}, it didn't work, I tried so many other things but not successful.

One possible solution:

rm -r $(seq $a $((a+3)))

(Provided you really meant what you illustrated with your code sample, ie. directories above or equal to $a and below or equal to $a+3, instead of what you wrote in the text, "above >$3 but below <$3+2".
