Incremental Numbering whitin a formula

[Guest]

I need to exctract data from another sheet but I need to do it for every
third cell.

My formula so far cell A2: =Sheet3!A2
cell A3: =Sheet3!A5
cell A4: =Sheet3!A8

etc.

How can I copy this down with the cells as it's not copying down correctly
at the moment?

In A2 enter:

=INDIRECT("Sheet3!A"&3*ROW()-4)
and copy down

 

[Guest]

=OFFSET(Sheet3!$A$2,(ROW()-2)*3,)

 

[Guest]

One way

In A2:
=OFFSET(Sheet3!A$2,ROWS($1:1)*3-3,)
Copy down as far as required

Thanks a bunch. It works briliantly

In A2 enter:

=INDIRECT("Sheet3!A"&3*ROW()-4)
and copy down

Here's the next part of the puzzle Cell I2:
=IF(Sheet3!A2=Sheet3!A1,Sheet3!E3,Sheet3!E3)

Cell I3:
=IF(Sheet3!A5=Sheet3!A4,Sheet3!E6,Sheet3!E6)

the cell wich the data is fetched from, eg. Sheet3!E3 has to increase be
increments of 3

There is another problem I have how do I do incremental number in a formula
after certain conditions are met?

e.g. =IF((VLOOKUP(A7,Sheet3!$1:$65536,5,FALSE))=G7,Sheet3!E18,FALSE)

the next cell in the colum should have the following formula:

=IF((VLOOKUP(A8,Sheet3!$1:$65536,5,FALSE))=G8,Sheet3!E21,FALSE)

How do I get the formula to read in increments of 3?

Just replace "Sheet3!E18" in this expression:

=IF((VLOOKUP(A7,Sheet3!$1:$65536,5,FALSE))=G7,Sheet3!E18,FALSE)

with this: OFFSET(Sheet3!E$18,ROWS($1:1)*3-3,)

ie use:
=IF((VLOOKUP(A7,Sheet3!$1:$65536,5,FALSE))=G7,OFFSET(Sheet3!E$18,ROWS($1:1)*3-3,),FALSE)
then copy down
