Sometimes, TSQL is the way to go. I would use ExecuteQuery here:

    var data = db.ExecuteQuery(@"
SELECT * FROM 
(SELECT *, ROW_NUMBER() OVER (ORDER BY id) AS [__row]
FROM [YourTable]) x WHERE (x.__row % 25) = 1");

You could also swap out the n:

    var data = db.ExecuteQuery(@"
DECLARE @n int = 2
SELECT * FROM 
(SELECT *, ROW_NUMBER() OVER (ORDER BY id) AS [__row]
FROM [YourTable]) x WHERE (x.__row % @n) = 1", n);
