It is a relative reference. If the formula =A1+A2 is copied to B1 then the formula changes to =B1+B2
What determines what type of reference a cell is, is how it is typed, not what happens when you copy it. It is the type of reference that influences how it changes when it is copied, not the other way around. If the formula does not change at all, it would be an absolute reference. The cell references would all have 2 dollars, like $C$5. If it does change, it can be either a mixed or a relative reference. A mixed reference will have one dollar sign, either $C5 or C$5. What direction it is copied will and how it changes, is determined by which dollar you have. The first dollar locks the column, and the second dollar locks the row. A relative reference has no dollars. Copying a formula from C13 to D13, will change the column references only, so if the cell reference is the first kind of mixed, then it won't change.

The Name Box. If you type in a cell reference in the Name Box, and press Enter, it will bring you to that cell. You can also press F5 to open the Goto dialog box and use that to go to a particular cell too.
