Answer:
Let 'a' be an even positive integer.
Apply division algorithm with a and b, where
where 0≤r<2
where r = 0 and r = 1
since 'a' is an even positive integer, 2 divides 'a'.
Hence, a=2q when 'a' is an even positive integer.
(ii) Let 'a' be an odd positive integer.
apply division algorithm with a and b, where
where 0≤r<2
Hence, a=2q+1 when 'a' is an odd positive integer.
Hence, Proved.
