This should be a relatively simple one.

Basically as you can see from the images below i have "h2"; then "h10" then "h18"

All i want is to be able to quickly auto fill however when i try to auto fill with the current conditions it doesn't follow the logic of the next cell being "h26"; i'd be open to using some VBA if there is not a simple function for this.
