Question

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

Answer 1

Answer:

When

q=1 we get 6

q=2 we get 10

q=-3 we get 14 and so on

So, all the number of the form 4q+2 will give only even numbers which are not multiple of 4.

Hence, every positive number cannot be written in form of 4q+2.

Answer 2

Answer:

No

Step-by-step explanation:

4q+2 = 2(2q+1) where 2q+1 is the form of odd integers and multiplication with 2 always gives us an even integer(+ve or -ve).
