Something like this perhaps (I'm just guessing on the rank)...

-- Sample data

DECLARE @table TABLE ([Year] int, Region varchar(20));

INSERT @table VALUES (2013, 'South'), (2014, 'North'), (2015, 'South'), (2015, 'North');

--Review:

--SELECT * FROM @table;

WITH

E1 AS (SELECT N FROM (VALUES (1),(1),(1),(1),(1),(1),(1))t(N)),

iTally AS (SELECT N = ROW_NUMBER() OVER (ORDER BY (SELECT NULL))-1 FROM E1 a, E1 b)

SELECT [Year], Region, t = (-6 + (.25*N)), [rank] = DENSE_RANK() OVER (ORDER BY [year])

FROM iTally

CROSS JOIN @table

ORDER BY [Year], Region, t-- ORDER BY Not required, including for display only, remove this for better performance
