Might not be the easiest way but if you create another column to the right
of the column you want to sum and enter the following formula in each cell:
=IF(MOD(ROW(),2)=1,,RC[-1])
This divides the row number by 2 and if there is a remainder, it concludes
that the row number is an odd number and gives the answer 0. If the row
number is even it copies the value from the preceding column. Now all you
have to do is Sum the new column to get total for every odd row.

If you want every even row instead, then use
=IF(MOD(ROW(),2)=0,,RC[-1])

Someone may well come up with something simpler but maybe this will do for
the time being
