checking invoice number not correct

hello,

I have the following script to check the invoice number is in order or not.
However, it cannot show out the correct information. My expect output show below and I would like to only list out the NOT IN SEQUENCE inovice number (not included "ok")

#!/bin/sh
start=1
for file_number in `ls -1 /appl/appl/archive/client/CACHE/CLIENTINVOICE*[0-9].archived | sort | cut -c 48,49,50,51`
do
if [ $start -eq 1 ] ; then
# this is the first pass of the loop, so we've got nothing to compare
start=0
previous=$file_number
else
# this is not the first pass of the loop
previous=`expr $previous + 1`
echo "comparing $file_number and $previous ... "
if [ $file_number = $previous ] ; then
echo "OK"
else
seqno=`expr $file_number - 1`
echo "CLIENTINVOICE$invoiceno are not in sequence "
fi
fi
previous=$file_number
done


input:
01185
01191
01192
01193
01196
01197
.
.
.

script output:
01190 are not in seq
01195 are not in seq

expect output
01186 are not in seq
01187 are not in seq
01188 are not in seq
01189 are not in seq
01190 are not in seq
01194 are not in seq
01195 are not in seq

NAME
seq - print a sequence of numbers SYNOPSIS
seq [OPTION]... LAST seq [OPTION]... FIRST LAST seq [OPTION]... FIRST INCREMENT LAST DESCRIPTION
Print numbers from FIRST to LAST, in steps of INCREMENT. -f, --format=FORMAT use printf style floating-point FORMAT -s, --separator=STRING use STRING to separate numbers (default: ) -w, --equal-width equalize width by padding with leading zeroes --help display this help and exit --version output version information and exit If FIRST or INCREMENT is omitted, it defaults to 1. That is, an omitted INCREMENT defaults to 1 even when LAST is smaller than FIRST. FIRST, INCREMENT, and LAST are interpreted as floating point values. INCREMENT is usually positive if FIRST is smaller than LAST, and INCREMENT is usually negative if FIRST is greater than LAST. FORMAT must be suitable for printing one argument of type `double'; it defaults to %.PRECf if FIRST, INCREMENT, and LAST are all fixed point decimal numbers with maximum precision PREC, and to %g otherwise.
