proc sql;
select state,qtr,bal_rev,avg(amount) as Avg_amount,sum(amount) as sum_amount from
(select *,
case when period in (1,2,3) then 'qtr1'
when period in (4,5,6) then 'qtr2'
end as qtr from have)
group by bal_rev,state,qtr;
quit;

If your sample data looks "exactly like" what you presented, here is one easy way:

data want;
set have;
sum+amount;
count+1;
if mod(period,3)=0 then do;
average=divide(sum,count);
output;
sum=0;
average=0;
count=0;
end;
drop count;
run;
