I have a field starting at B3 that is e.g. "28/11/2016" and every field beside it needs to be incremented to be a week after that.
Currently, I am doing this manually, i.e. =B3+7
then =B3+14
and so on.
I'm quite inexperienced with Google Sheets and can't find a format tool that will help me do this. Ideally, I would need to have a formula that will take the cell before and add a week onto it.
So what you can do is B3 => =DATE(2016,11,28)
and B4 => B3+7
and then select B4 and drag through bottom you will have dates in increment of weeks.
