For the first week of our Math pre-calculus class, we have learned about arithmetic sequences and series. I had been familiar with arithmetic sequences, but had never learned about series’, and the equations and calculations that create them. I learned about the formulas you can use to find the necessary numbers for solving a full arithmetic sequence and series.
Such as : = + d(n – 1) to solve the value of a term you don’t know yet.
or : = ( + ) to solve the sum of a certain amount of terms in a series.
Both of these help out a ton in solving these patterns.
Another thing I learned, that will help out lot’s in the future, is that an equation without powers is a linear equation.
Example : 17- 5n + 5 = -38 will be a linear equation as there are no powers in it.
