Click on the line where you want to start the new numbering sequence.
From the Format menu, select Bullets and Numbering.
In Restart numbering at, enter the starting number.
Tip: If you are formatting an alphabetical list rather than a numbered list, type the numerical equivalent for the start letter. For example, if the list should start with the letter G, enter 7 in Restart numbering at.
Click OK. The list is renumbered sequentially, beginning with the line where the insertion is located.
