Intro to Calculus Week 2 Homework

Hello,


I was told one of my answers for last week's homework was wrong, but I'm not sure why. It is different than what was on the answer key, but I still think it is mathematically correct. 


The problem was to prove using mathematical induction that 2 + 2^2 + 2^3...+2^n = 2((2^n )-1). This was my answer. answer

You are correct, William. That problem should have been marked as correct. Your feedback and grade have been updated for this homework assignment. Thanks for pointing this out!
