    I have not been able to find a video on this concept that was so well-explained, thorough, and REASSURING. It's one thing to understand the material and make a video about it, but it's another thing to be able to teach it as thoughtfully as you did. Thank you SO much.

    I was literally scribbling all over my homework panicking again, because I did not understand this at all from the class I had. After watching this video omg I feel so much better! It's because of people like you offering this help on youtube for free that one day I'll be able to get my engineering diploma. Thank you so much!

    At 30:16, the denominator inside the sum should be 5^n, not 5^n+1. I used this to help with some homework and it didnt work with 5^n+1, but did work with 5^n even with n=0...

    • @mathwithprofessorv

      No, you’re incorrect. I brought the 5 outside of the sum inside with 5^n, making it 5^(n+1).
