the fugg bruuh, i spent 30 minutes to solve this kata and when i see your solution, i think i have to quit programming

Lol! I felt the same.

Study math

I didn't want to feel cheesy by googling "pyramid of odd numbers" and being given a solution, but after one hour of struggle and coming to a different solution... This is borderline insulting.

I came up with the same solution but I genuinely tried various approaches before this. I love mathematics because there is always an alternative pattern to recognize and you can tackle problems from various angles. I think I gave this about ~2 hours before I just realized what I need to do but I actually enjoyed this.

No...way..

What do you all recommend as resources for becoming better at recognizing such patterns?

mate i was so close to this answer in my mind, after for an hour i still can't figue out how, bravo.

LoL) Math is a power :)

I feel stupid 🤐

The same. And I'd also like to know if it's universal with other arithmetic progressions.

Yes! It took me about 3 hours of observation to see the pattern.
P.S. Hint, maybe. Not a spoiler.

There are people who can't do math, so...

Ok, I wish my math knowledge would be that good.
But imo finding the alghorithm yourself, brings you more benefit (if you are a programmer)
