Using Libre Office Calc (3.5) and have a question.

When copying a formula that references cells into multiple empty cells the default is to increment each cell reference by one column or row, depending on the direction that the formula is being drug.

A formula '= 1 + A1' drug horizontally changes to '= 1 + B1' when pulled one cell to right and '=1 + A2' when pulled one cell down.

Is there a way to control increase the increment of the referenced cell? Is is possible to have a formula '= 1 + A1' that effectively changes to '= 1 + A3' when drug down one cell, '= 1 + A5' when drug down two cells, etc?

If it matters, I am trying to take a constantly updating master list of data that is organized by dates (Wednesdays and Saturdays) and create separate spread sheets for each day of the week that can be updated by only pulling down the formula into the next cell. My attempts at using the 'lookup' function, 'offset' function, and creating a sort column in Libre Office Calc are thwarted by my inability to figure out how to get around the single step increment when pulling a formula down into the next cell.

Thanks
