To Show:-
- Show that any positive odd integer is of the form 6q + 1, or 6q + 3, or 6q + 5 Where q is some integer.
AnSwer:-
Let a be a given integer.
On dividing a by 6 ,
we get q as the quotient and r as the remainder such that
★ According to Euclid Division lemma:
→ a = bq + r
Putting value of b as 6:-
a = 6q + r,
where, r = 0,1,2,3,4,5
when r = 0,
a = 6q, even no
when r = 1
a = 6q + 1, odd no
when r = 2
a = 6q + 2, even no
when r = 3
a = 6q + 3,odd no
when r = 4
a = 6q + 4,even no
when r = 5,
a= 6q + 5 , odd no
Therefore, we can say that,
Any positive odd integer is of the form 6q+1, 6q+3 or 6q+5.

Let a be the positive odd integer which when divided by 6 gives q as quotient and r as remainder.
according to Euclid's division lemma
a=bq+r
a=6q+r
where , a=0,1,2,3,4,5
then,
a=6q
or
a=6q+1
or
a=6q+2
or
a=6q+3
or
a=6q+4
or
a=6q+5
but here,
a=6q+1 & a=6q+3 & a=6q+5 are odd.
