See if this works fo you:

B1 = manually entered 1000

Enter this formula in B2 and copy down as needed:

=COUNT(B$1:B1)*5+1000

Sorry Don, that doesn't work at all. 1) I do NOT want to delete the row
which
contain other data it's only the cell that is blank. 2) Even when I
delete a
row e.g B2, B3 does not autimatically change from 1010 to 1015.

in b2=row()*5+1000 and copy down
Then DELETE the blank row(s)

I have the following number series:
B1=1000
B2=1005
B3=1010
B4=1015
B5=1020
B6+1025
etc etc all in increments of 5. However, I have some completely
random
cells
in the same column that I must leave blank. Since I used the fill
handle
to
copy down the number series, how can I delete random cells and have
the
number series readjusted automatically e.g as follows:
B1=1000
B2=blank
B3=1005
B4=1010
B5=blank
B6=1015
Greatly appreciate your help. Excel 2003.
