LUCK IN ODD NUMBERS
Perhaps the old saying, “there is luck in odd numbers,” may have some connection with the curious fact that the sum of any quantity of consecutive odd numbers, beginning always with 1, is the square of that number. Thus:—
| 1 + 3 + 5 | = | 9 | = | 3 | × | 3. |
| 1 + 3 + 5, etc., up to 17 | = | 81 | = | 9 | × | 9. |
| 1 + 3 + 5, etc., up to 99 | = | 2500 | = | 50 | × | 50. |
