Algebra 2 – Proof by Mathematical Induction

Why are students always like, "PROOFS?? NO!!!!!" It's funny, the system has hijacked them from us well-intended educators. Time to take them back. In this case, we prove equations true by mathematical induction. That basically means, "if the next item in the list fits, then the rule that makes the list must be true." You'll see what that means, YAY MATH!

Yay math i wanna sign up for 95 and 120 can u help me

[zenzmatic]

how come its k(2k+1) i thought u factored out k+1 from all the factors

Proof by induction of n being true then n+1 being true proves it true for ALL n.
