Calculate the sum of the following
The first 9 Natural Numbers
Σ n Natural Numbers formula:
| S9 = | n(n + 1) |
| 2 |
| S9 = | 9(9 + 1) |
| 2 |
| S9 = | 9(10) |
| 2 |
| S9 = | 90 |
| 2 |
S9 = 45
Average (A) of the first 9 Natural Numbers
| A = | Sum of the first 9 Natural Numbers |
| Count |
| A = | 45 |
| 9 |
Average (A) of the first 9 Natural Numbers = 5
