Question 2: 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 take a as any positive integer and b = 6. 
Then using Euclid’s algorithm we get a = 6q + r here r is remainder and value of q is more than or equal to 0 and r = 0, 1, 2, 3, 4, 5 because 0 <= r < b and the value of b is 6 
So total possible forms will 6q+0 , 6q+1 , 6q+2,6q+3,6q+4,6q+5
6q+0 6 is divisible by 2 so it is a even number 
6q+1 6 is divisible by 2 but 1 is not divisible by 2 so it is a odd number 
6q+2 6 is divisible by 2 and 2 is also divisible by 2 so it is a even number 
6q+3 6 is divisible by 2 but 3 is not divisible by 2 so it is a odd number 
6q+4 6 is divisible by 2 and 4 is also divisible by 2 it is a even number
6q+5 6 is divisible by 2 but 5 is not divisible by 2 so it is a odd number
So odd numbers will in form of 6q + 1, or 6q + 3, or 6q + 5
