Answer:

good evening,

You should notice that :

n=4K or n=4K+1 or n=4K+2 or n=4K+3

If n=4k so n(n+1)(n+2)(n+3)is a multiple of 4

If n=4K+1 so n+3 =4(k+1) so n(n+1)(n+2)(n+3)is a multiple of 4

If n=4K+2 so n+2 =4(k+1) so n(n+1)(n+2)(n+3)is a multiple of 4

If n=4K+3 so n+1=4(k+1) so n(n+1)(n+2)(n+3)is a multiple of 4
