    Proof by Induction??

    First off I wanted to say thank you for all those who read this and offer help.

    I am trying to prove that 1+2+3.... = n(n+1) / 2

    So far I have that
    1) Base Case - Prove for n=1 so 1(1+1) / 2 = 1

    sorry didn't mean to send it ...

    So next step -- Proof by Induction I have Assume the Assertion is true for n = K .. and show that if follows the assumption that the assertion is true for n = K +1 what i am lost on is where we get

    1 + 2 + 3 ....+(K+1) = (K+1) (K+2) / 2 than what does it go to??
