I tried this and it works well ... with the exception that I need to put other info into the cells in between. That's why I wanted to try addition for the cell reference ...

sheet 2 cell A1 --- =sheet1!(A1)

sheet 2 Cell A3 --- =sheet1!(A1+1) jumps down 1 row on Sheet1

sheet 2 Cell A5 --- =sheet1!(A1+2) jumps down another row on Sheet1

sheet 2 Cell A7 --- =sheet1!(A1+3) jumps down another row on Sheet1

Similar to copying a pattern or formula.
