Calculate the sum of the following
The first 10 Square Numbers
| S10 = | n(n + 1)(2n + 1) |
| 6 |
| S10 = | 10(10 + 1)(2(10) + 1) |
| 6 |
| S10 = | 10(11)(20 + 1) |
| 6 |
| S10 = | 10(11)(21) |
| 6 |
| S10 = | 2310 |
| 6 |
S10 = 385
| A = | Sum of the first 10 Square Numbers |
| Count |
| A = | 385 |
| 10 |
Average (A) of the first 10 Square Numbers = 38.5
