WebSep 5, 2024 · There is another way to organize the inductive steps in proofs like these that works by manipulating entire equalities (rather than just one side or the other of them). Inductive step (alternate): By the inductive hypothesis, we can write ∑k j = 1j = k(k + 1) 2. Adding (k + 1) to both side of this yields ∑k + 1 j = 1j = (k + 1) + k(k + 1) 2. WebOct 5, 2024 · Induction Proof - Summary So, we have shown that if the given result [A] is true for n = m, then it is also true for n = m +1 where m > 1. But we initially showed that the given result was true for n = 1 so it must also be true for n = 2,n = 3,n = 4,... and so on. Induction Proof - Conclusion
