Try this formula in C1 and then copy it down...

=A1+INDEX(B1:B5,6-ROW(A1))

Assume I have numbers in cells A1:A5 and B1:B5. I would like to add them
in column C, but following this formula: C1=A1+B5, C2=A2+B2,...,C5=A5+C1.
How do I do it so that I can just use copy paste of this formula without
manually re-entering it in every cell? Thanks.
