Why do you think (ii) is not valid for n=1?View attachment 20540
Hi everyone I have solved question 1 but not quite sure of question 2 as when n=1 in base case it is not valid and am not sure how to continue. Any help would be greatly appreciated.
12+(2*1)2=5Thank you for the reply.
I substituted in n=1 into both sides
2(1)^2 = 1(2(1)+ 1) (4(1) + 1)/ 3
The left side equals 4 and then right side of the equation is 5. I am not quite sure as to how both sides can equal 5.
