If all that is wanted is to sum the odd-numbered rows:
=SUMPRODUCT((B2:B32)*(MOD(ROW(B2:B32),2)))
or the even-numbered rows:
=SUMPRODUCT((B2:B32)*(1-MOD(ROW(B2:B32),2)))
Of course this is less flexible than your formula, which allows one to do
every 3rd or 4th row,
etc.

Troy,
Do you want a formula?
This formula will sum every nth value from the mth item in the range,
assuming in this case a range of B2:B32. Just change m and n to your
values
(1 and 2 in your case), and all references to the applicable range
=SUMPRODUCT((B2:B32)*(MOD(ROW(B2:B32)-ROW(B2),n)+1=m))
