For the first week of our Math pre-calculus class, we have learned about arithmetic sequences and series. This was all new to me as I have never heard of it or learned it before . I learned about the formulas you use to solve arithmetic sequences and series.

You can use = + (n-1)(d) to solve the value of a term you don’t know yet.

Another thing I learned is an equation like  13- 4n + 3 = -26 will be a linear equation as there are no powers in it.
