lets take 5

also takje 13 we get 168 which ius divuisiuble

n^2=4m^2+1+4m

n^2-1=4m^2+4m

=4m(m+1)

Let K=m(m+1)

if m is odd number, odd*even will give u even number,

If m is even number even into odd will give u even number.

So K is always even no matter what is the value of m.

and even multiple of 4 will always divisble by 8
