Arthur needs to copy the formula in cell c13 to cell d13. he needs cell d13 to have the same formula but referenced with a new location. which type of cell reference should he use?

By default, all cell references are relative references. When copied across multiple cells, they change based on the relative position of rows and columns. For example, if you copy the formula =A1+B1 from row 1 to row 2, the formula will become =A2+B2. Relative references are especially convenient whenever you need to repeat the same calculation across multiple rows or columns.
