Hi, the question I have is:
a) Use mathematical induction to prove that
b) Deduce that
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 (Happy)

fine so far.
