Question

3. show that every positive even
integer is of the
from 2q and thatevery positive odd integers as
of the form 2q+1, where 'q' is some integer​

Answer 1

let a and b be the any positive integer then by euclids division algorithm a= bq+r where r is equal to 0 or less than 0 and less than b

here b=2

if R=0 1 2 3

a= b(2)+0

then a=2b

if r= 1

a=b(2)+1

than a=2b+1
