What multi-row formula can I use to subtract every other row from the one before it? The result column is what I need. For example, Value 8-6=2, Value 4-3=1, Value 2-6=-4
| Set | Value | Result |
| 1.2 | 6 | |
| 1.6 | 8 | 2 |
| 1.2 | 3 | |
| 1.6 | 4 | 1 |
| 1.2 | 6 | |
| 1.6 | 2 | -4 |
| 1.2 | 6 | |
| 1.6 | 8 | 2 |
| 1.2 | 3 | |
| 1.6 | 5 | 2 |
| 1.2 | 7 | |
| 1.6 | 4 | -3 |
