If "autonumber" really means an IDENTITY column then this looks like a
very silly and impractical design. What exactly is this data supposed
to represent?

Apparently you want to sum pairs of rows:

SELECT A.autonumber, B.autonumber
A.value+B.value AS tot
FROM tbl AS A
LEFT JOIN tbl AS B
ON A.autonumber + 1 = B.autonumber
WHERE A.autonumber IN (1,3,5,7,9) ;

(untested)

The problem is that you can't prevent gaps in the sequence of values in
an auto-numbered IDENTITY column. So there is no guarantee that each
row will have a "next" row.

Whenever possible please post enough code to reproduce your problem.
Including CREATE TABLE and INSERT statements usually helps.
State what version of SQL Server you are using and specify the content
of any error messages.

What class are you taking that this is homework for????

thanks for your information, but if i want increment 7 i try syntax :
SELECT A.autobaris, B.autobaris AS Expr1, A.nilai + B.nilai AS tot
FROM ac A LEFT OUTER JOIN
ac B ON A.autobaris + 4 = B.autobaris
and the result :
autobaris exp1 tot
1 4 9
5 8 22
9 null null
but i want the result :
autobaris exp1 tot
1 4 20
5 8 44
9 10 18
please help thanks

Ummm, why A.autobaris + 4 if you want an increment of 7? shouldnt you
specify A.autobaris + 6?
