With a 15, yes.
With bigger values, there is a chance that the background process terminated and, as the system PIDs cycle, there is another process with the old PID. And you don't want to kill that
If you have a shell with job control, you can use the safer kill %1.

Unix standard shells do not have job control.
I am just thinking about another background process:
#!/bin/csh
# This program will add integers
#
#
# add integer1 ..
#
# Check for argument
if ($#argv == 0 ) then
echo "usage: add integers"
exit 1
else
set input = $argv
endif
#
set sum = 0
foreach var ( $input )
@sum = $sum + $input
end

bose descriptions explaining the output.
