Prove that P(1) is true:
Now assume P(k) is true. We must show that this implies
So, we have that:
Can you go on from that?
Hey guys having some trouble with this question I just don't really know where to go with it..
Use mathematical induction to prove that, for all integers n ≥ 1
n
2^(j-1) = (2^n)-1.
j=1
thanks for any help you can give
