Yes.
A composite number is a positive integer which has a positive divisor other than one or itself. In other words a composite number is any positive integer greater than one that is not a prime number.

11 is a prime number so it became odd member of the series.
Any number which is divisible by 1 and itself is a prime number, and any number which is not prime is called a composite number.
But one does not belong to both these categories i.e., prime or composite.

If any number has more then two factors(1 and that number itself) then that number is called composite number.
Example:
9 has 1,3,9 as factor ,so its composite number.
11 has 1,11 as the factor so it is not composite number since it is divisible by 1 and by that number itself.

Composite no. Means it is divisible by its factor &itsself also or having more than 2 factors.
Its very clear 4, 6, 8, 10, 12, 9 has more than 2 factor but 11 has only 1&11.

Tell me clearly what is the composite number?

9 has 3 factors : 9, 3, 1 so it is composite number.
But 11 has not any other factor except 11 and 1.
So it is not a composite number, it is a prime number.
But 11 has not any other factor except 11 and 1.
So it is not a composite number, it is a prime number.
