Eg. 1, 2, 2, 4, 5 mode=2 Median is the middle value when data is arranged in ascending or descending order. eg. 1,3,4,7,8 Median=4 (middle value)

for P(1)= 1 2×6=12 which is multiple of 3 It is true then For P(K) = K(k+1) (k+5)=(k2+k) (k+5)=k3+5k2+k2+5k k3+6k2+5k =3m (where m is an integer) k3= 3m-6k2-5k Now for P(k+1)= K+1(k+2)(k+6) =on multiplying we get k3+9k2+20k+12 put k3= 3m-6k2-5k 3m-6k2-5k+9k2+20k+12 3(m-k2+5k+4) Hence P(k+1) is true And where n ~ natural no.
