Proof of finite arithmetic series formula by induction

WebProof. This can be seen by induction on k. G1 is triangle-free since it has a single vertex. Gk+1 is obtained from the disjoint union of copies of G1,G2,...,Gk, which by the induction hypothesis is triangle-free, by adding vertices adjacent to an independent set. Indeed each new vertex b in Gk+1 is adjacent to at most one vertex in each copy of ... Webevery value of k. In other words, if domino number 0 falls, it knocks over domino 1. Similarly, 1 knocks over 2, 2 knocks over 3, and so on. If we knock down number 0, it’s clear that all the dominoes will eventually fall. So a complete proof of the statement for every value of n can be made in two steps: ﬁrst, show that if the tempered glass mohs scale
