Retrieve First Value from Cells Above

[tsroque]

I have a list of dates with blank cells in between at various spaces. I need to add 7 days to the date above it no matter it's location (not the last value in the column). Is this the most effective formula I can use to do this? Sometimes it seems to get hung up and not calculate. Here's an example of the formulas and process I'm using...

(first date is in A3)
A3: 1/1/2019
A15: =(LOOKUP(2,1/(ISNUMBER($A$3:A14)),$A$3:A14))+7
A21: =(LOOKUP(2,1/(ISNUMBER($A$3:A20)),$A$3:A20))+7
A38: =(LOOKUP(2,1/(ISNUMBER($A$3:A37)),$A$3:A37))+7
.
.
.
.
A200...

Thank you!
