    P(n): 2 + 4 + 8 + ... + 2n = 2(n + 1) - 2 P(k): 2 + 4 + 8 + ... + 2k = 2(k + 1) - 2 P(1): 2 + 4 + 8 + ... = 2n = 2(1 + 1) - 2

    P(k): 2 + 4 + 8 + ... + 2k = 2(k + 1) - 2 replace k by k+1 P(k+1):2 +4+8+2(k+1)=2(k+1+1)-2

    So P(k + 1): 2 + 4 + 8 + 2(k + 1) = 2(k + 1 + 1) - 2???

    Where would that go? P(k + 1): 2 + 4 + 8 + ... + 2(k + 1) = 2(k + 1 + 1) - 2 Is that right?
