Try one of these commands:
Code:
sed "$var"'s/$/\\\n\t2a/'

or
Code:
sed "$var s/$/\\\\\n\t2a/"

The shell interpretes one of the backslash as an escape character if you use double quotes.
Try to echo the sed command to see what happens:

Code:
$ var=2
$ echo "$var s/$/\\\n\t2a/"
2 s/$/\\n\t2a/          <- missing one backslash

and now with the above commands:
Code:
$ echo "$var s/$/\\\\\n\t2a/"
2 s/$/\\\n\t2a/
$
$ echo $var's/$/\\\n\t2a/'
2s/$/\\\n\t2a/
