Question
Let K, be the complete graph on n vertices. a) Draw K, for n = 1, 2, 3, 4, 5. For each, how many edges are there? b) Let E (K„) denote the number of edges in K. Write a recurrence relation for E(Kn) along with initial conditions. (You do not need to prove this formula is correct) c) Guess an explicit, non-recursive formula for E (Kn) and use induction to prove it using the recurrence relation from part b. That is, assume the recurrence relation is true and use it to prove the explicit formula.
