Arithmetic+Sequences

__**Arithmetic Sequences**__
by: Melissa


 * What are __arithmetic sequences__:**

Arithmetic sequences are sequences of numbers that follow a pattern by adding a repetitive number to each term to find the next. If you add 2 to each term, you will continuously find the next number.
 * EX:** 2,4,6,8,10


 * How to calculate the __"nth"__ term:**

In order to find the "nth" term in a sequence, you must create a chart by predicting terms.
 * EX:**

You must find the common difference in the above example. In that case, it would be 2 because by adding 2 to each number, you would find the next term.

Lets say you are looking for the 6th term in that sequence. To find it you would write the formula: **f(n)= 2(n)-1** and use "n" as your variable.


 * __Note:__** **f(n)** stands for the "nth" term.

To find the 10th term you would use the formula: **f(10)=2(10)-1** Note: **f(n)** stands for the "nth" term.

f(10)= 20-1 f(10)=19
 * EX:**f(10)= 2(10)-1
