can i take this course with some basic math skills?

on introduction to proofs and induction, they’re asking to set the variable “guess” to the sum of the first 4 positive odd integers given 2i. so that would be 2(1) + 2(3) + 2(5) + 2(7) or 2 + 6 + 10 + 14, which is 32. however, the exercise is saying the answer is 25.

We are not being asked to apply the constraints given in the narrative (2 * i), just to sum the first five odd numbers that we are aware of from the counting sequence we learned as school children (Natural numbers).

1 + 3 + 5 + 7 + 9

It’s a guess because we’re doing it in our head, not on paper or by otherwise mechanical means. Induction is a real time thought process. We think it.

Computers can by no means replicate this, even with all the power of AI. It’s still our one true domain over the machine.

cool, thanks for the reply.
