Answer -
Solution:
No, every positive integer cannot be of theform 4q + 2, where q is an integer.
Justification:
All the numbers of the form 4q + 2, where тАШqтАЩis an integer, are even numbers which are not divisible by тАШ4тАЩ.
For example,
When q=1,
4q+2 = 4(1) + 2= 6.
When q=2,
4q+2 = 4(2) + 2= 10
When q=0,
4q+2 = 4(0) + 2= 2 and so on.
So, any number which is of the form 4q+2 willgive only even numbers which are not multiples of 4.
Hence, every positive integer┬аcannot┬аbewritten in the form 4q+2
