6. Select a formatting style and click OK.


Explanation: the MOD function gives the remainder of a division. The ROW() function returns the row number. For example, for the seventh row, MOD(7,2) equals 1. 7 is divided by 2 (3 times) to give a remainder of 1. For the eight row, MOD(8,2) equals 0. 8 is divided by 2 (exactly 4 times) to give a remainder of 0. As a result, all odd rows return 1 (TRUE) and will be shaded.
