Given n is a positive integer so submit n=1,2,3,4,5,6,7,8.....
and it is also given that (n+1)(n+3) is odd this statement is true only for values of n=2,,4,6,8 i.e, even numbers.
submit n=2,4,6,8 in (n+2)(n+4)
for n=2 (n+2)(n+4)=24
for n=4 (n+2)(n+4)=48
for n=6 (n+2)(n+4)=80
for n=8 (n+2)(n+4)=120
from above we can say that all 24,48,80,120 are all divisible by 8 hence answer is 8
