I was given the problem: For n [tex]\geq[/tex] 1, 2 + 2[tex]^{2}[/tex] + 2[tex]^{3}[/tex] + 2[tex]^{4}[/tex] + ... + 2[tex]^{n}[/tex] = 2[tex]^{n+1}[/tex] – 2.
I did the induction on it and got 2[tex]^{k+2}[/tex]-2. I know this is the right answer but I don't know WHY. Could anyone explain it to me?
