Let us add consecutive odd numbers and try to find any relationship.
1. 1
2. 1+3 = 4 ( square of 2 i.e
)
3. 1+3+5 = 9 (
)
4. 1+3+5+7 = 16 (
)
5. 1+3+5+7+9 = 25 (
)
6. 1+3+5+7+9+11 = 36 (
)
7. 1+3+5+7+9+11+13 = 49 (
)
If we notice, the sum of the consecutive odd integers in each case is equal to the square of the place where it lies. For example, the sum of numbers in seventh place is equal to
. The sum of the numbers in the fifth line is equal to
.
For the first one t could be a volcano that’s slowly caving in over time, and for the 2nd one it could be a store that’s selling something, and the cost per person was bigger when there was less people, but since more people came they didn’t have to charge as much ^ ^
