Hi, the question I have is:

a) Use mathematical induction to prove that

for n=1,2,3...

b) Deduce that

for n=1,2,3...

justify your answer.

For a) I have the following, so far:

Let p(n) be the variable proposition

For n=1, the sum is

The right hand side gives:

So p(1) is tue.

Assuming p(k) is true, I get:

next I tried to deduce that p(k+1) is true, that is:

Is this right so far?

Thanks for your help
