And prime numbers:

Odd number and prime number are two different concepts. Odd numbers may or may not be prime numbers. For example, 3 is an odd number and a prime number; 9 is odd, but not prime.

The sequence: 1, 3, 5, 7, 9, ..., 2n- 1, ... is called an odd sequence, and the general term formula is. It has a very beautiful property: when n takes any positive integer, the sum of its first n terms is a complete square number, that is? Odd columns can also be expressed in another way: if there were both at that time, then the series is an odd column. ?
