Hence the result is true for n = k +1 if it is also true for n =k

Hence the result is true for n = k +1 if it is also true for n =kSince the result is true for n = 1 then it is also true for n =1+1 i.e. n=2, and since the result is true for n = 2 then it is also true for n =2+1 i.e. n=3, and so on for all positive integral values of n

Hence the result is true for n = k +1 if it is also true for n =kSince the result is true for n = 1 then it is also true for n =1+1 i.e. n=2, and since the result is true for n = 2 then it is also true for n =2+1 i.e. n=3, and so on for all positive integral values of n
