I'm going to an online college, and one of the common homework themes is to do the even or odd numbered problems in a textbook. Putting in the numbers starts an auto format list, but it advances the numbers up by one. Thus far, my only options are to let it create a regularly numbered list, then change the numbers myself manually, or to turn off auto formatting to create the list manually myself.

Is there any way to create an auto numbered list that will only use even or odd numbers?
