[Not-so-daily puzzle] Triangle sequence

I think I've found out: 

pattern: For figure (f) even, there are more f gray triangles than white ones.  

| 1 | 2 | 3 | 4 | 5 | 6 | 7 |
|     :---:      |     :---:      |     :---:      |     :---:      |     :---:      |     :---:      |     :---:      |
| 1 | 1 | 6 | 6 | 15 | 15 | 28 |
| 0 | 3 | 3 | 10 | 10 | 21 | 21 |
|    | +2 |  | +4 |  | +6 |  |

Total triangle = 62500

62500/2 = 31250

gray = 31375
white = 31125

50,2%
