    I was pretty confused while studying the chapter Sequences and Series. Basically, what is an arithmetic sequence and what is an arithmetic series? Are they both the same thing?

    A series is the sum of a sequence.

    If a sequence is (a_1, a_2, ..., a_n), the corresponding series is a_1 + a_2 + ... + a_n.

    An arithmetic sequence is a sequence (1,2,3,4,5...) that goes up in a constant. Basically the difference between each term is the same, such as +2, (1,3,5,7,9) is an arithmetic sequence because we go up in 2 every time. Do you understand the Sn stuff?

    Yeah knowing the formula, but also being able to use it to work out the sum of a certain number of terms (n)
