Is this a homework question? I ask because I answered something almost identical to this a couple of days ago (here). . .

One way would be to do it like this: -

DECLARE @date DATETIME, @number INT

SET @date = '2011-06-06 00:00:00'

SET @number = 12

;WITH CTE AS (

SELECT 0 AS months

UNION ALL

SELECT months + 1

FROM CTE

WHERE months < @number-1)

SELECT DATEADD(MONTH,months,@date)

FROM CTE

You would need to format the result as you require.
