Handshake problem induction

WebApr 27, 2015 · Every arriving guest shakes hand with everybody else at a party. If there are n guests in the party, how many handshakes were there? Proof by using induction. My approach to this problem was to write down a list of values for n and the corresponding people shaking hands. For instance, for n = 4, let's say A shakes hand with B, C, and D; … WebThe point of induction is to show that this holds for $h=k+1$, i.e. $$x_1 + \cdots + x_n = 2(k+1)$$ when there are $k+1$ handshakes. For clarity you might say, for the inductive …
