Understanding Sequences and Series

Skibidi vibes in math class as we dive into sequences and series. A sequence is just a list of numbers vibing together under a rule, while a series is the sum of those numbers. Finite sequences are lowkey cool, like counting evens from 2 to 10, while infinite sequences go on forever, just like the goon squad. Arithmetic progressions? They are the sigma grindset of sequences, with each term adding a constant difference. So, if you have 3, 5, 7, and 9, the common difference is 2. Remember, the first term is a, the last term is l, and the number of terms is n. Stay dank and keep calculating!
