copy and past down formulas

Hi,
I am trying to copy and paste a formula down but when I go down two lines in my the calc sheet I need the formula to go just one line down on the workings tab
example

In cell M6=IF(LM!F5<0,LM!E5,LM!D5).
In M7 and M8, I have a few calculations
When I past the formula from M6 in M9, I need =IF(LM!F6<0,LM!E6,LM!D6)
However, Excel brings =IF(LM!F8<0,LM!E8,LM!D8)

Any ideas?

Best Regards,
Josvill

TRY

=IF(INDIRECT("lm!f"&ROW()/3+3)<0,INDIRECT("lm!e"&ROW()/3+3),INDIRECT("lm!d"&ROW()/3+3))

Assumptions is pattern of rows 6.9,12 etc

thanks Mangesh/John, when dragging down it doesn't do what I expect
I am uploading an example now.
I am also trying to replicate the same rule for T6. but to not avail.
Could you give me a hand please?Testing template formula.xlsx

If you drag the formula down you are going to replace M7 and M8 with the one in M6.

In M7 and M8, I have a few calculations

in M6

=IF(INDIRECT("lm!f"&INT(ROW()/3)+3)<0,INDIRECT("lm!e"&INT(ROW()/3)+3),INDIRECT("lm!d"&INT(ROW()/3)+3))

will place same formula in 6, 7 and 8 if dragged down

And rows 9, 10 and 11 will have next increment of "F"

now very confused.
