$a\geq 1$

Form of prime number:
$n = 6q + 1; 6q + 5$
where q is a non negative integer.
It will cover the most ot the prime number.

Hello student,
Any positive number should be written as $\left | x \right |$ .
This is the modulus function. The domain can be both positive or negative integer but the range will always be positive integer.
For the given numbers, 2q, 2q+1, … can be negative as well and similarly if we replace 2 by any number it may be positive or negative. So, if a number has to be strictly positive, it should be written as $\left | x \right |$ .
Regards
Sumit
