Use the 3 step Mathematical Induction process to prove the following statements. You must label and show all three steps. Step 1: Prove n = 1 is true Step 2: Assume true for all n = k Step 3: plug in k+1 and show it is true. 30 Points You choose any 3 to prove. 1. 12 + 32 + 52 +... + (2n- 1)2 - "(20-1)(2n+1) 2. Prove n' + n is always even. 3. Prove 32 - 1 is divisible by 8. 4. 36 + 324 + 900+... +(12n - 6) = 12n(An? - 1) 5. 13+ 2+ 3 +. .. the 1(+1) 2
