## How do you calculate odd numbers?

If 1,3,5,7,9,11,…, (2n-1) are the odd numbers, then;

1. Sum of first odd number = 1.
2. Sum of first two odd numbers = 1 + 3 = 4 (4 = 2 x 2).
3. Sum of first three odd numbers = 1 + 3 + 5 = 9 (9 = 3 x 3).
4. Sum of first four odd numbers = 1 + 3 + 5 + 7 = 16 (16 = 4 x 4).

## How do you find odd numbers?
