How to do the following copying?

[cyberdude]

Hi,

I have a spreadsheet in which

cell C2 contains =A1,
cell C3 contains =A3,
cell C4 contains =A5

may I know what operation I can do, without using macro, such that
cell C5 contains =A7, cell C6 contains =A9, cell c7 contains =A11
etc? Thank you.

Mike
