6. Prove that if 3m 2is odd, then so is n.

Given 3n+2 is odd. Now, we know if subtract even no. from a given no. it will reamain as previous one like even will remain even while odd will remain odd number. It means, 3n is also odd. Now, if divide 3n by an odd no., it will remain odd no since odd/odd = odd. If we divide 3n by 3 result will be odd. So, 3n/3 = n and it is odd. Hence proved.
