Is there a way to make a column of cells that links to another column but so that the row being linked increases by 3 each time instead of 1.

i.e.

Column A

Row 1: =B1
Row 2: =B4
Row 3: =B7
Row 4: =B10

etc., etc.

Whenever I try to drag down the formula, the order gets mixed up.

Thanks for any help!
