Explanation:
Exp: B
No
No, all positive integers cannot be written in the form of 4q + 2
Because, 4q + 2 = 2(2q + 1)
Therefore, 4q + 2 is an even number.
So, we can't write odd numbers in the form 4q + 2 (where q is an integer)Also 2q + 1 is an odd number, hence.
the maximum power of 2 that divides 4q + 1 is 1. Therefore, we can't represent the numbers divisible by 4 this form.
