Question

write whether every positive integer can be of the form 4q + 2 where Q is an integer justify your answer​

Answer 1

Its Simply not possible.

Because

4q + 2 = 2(2q + 1)

This means if a positive integer existed in the form of 4q + 2 then it needs to be an even integer. But not every integer is even.

Hence, every positive integer can be of the form 4q + 2 where Q is an integer is false because some are odd also
