Write whether every positive integer can be of the form 4q+2, where q is an integer. Justify your answer.

All the numbers of the form 4q+2, where 'q' is an ineger, are even numbers which are not divisible by '4'.

For example, when q=1, we get the number as '6'.

When q=2, we get the number as '10'.

When q=0, we get the number as '2' and so on.

So, all hte numbers of the form 4q+2 will give only even numbers which are not multiples of '4'. 

Hence, every positive integer can not be written in the form 4q+2
