Type response here

Finding the next terms is pretty easy, but what if I asked you to find the 54th term?

Or the 372nd term?

Never fear, I have a way for you to find ANY term :)

Multiple Choice

The formula for finding the $n^{th}$ term of the arithmetic sequence:

15, 13, 11, 9 ...

* what is the first term?
* what is the common difference?

$15+\left(n-1\right)\left(2\right)$

$9+\left(n-1\right)\left(2\right)$

$15+\left(n-1\right)\left(-2\right)$

Fill in the Blanks

Find 141st term of the arithmetic sequence: 15, 13, 11, 9...

1) Use the formula $a_n=a_1+\left(n-1\right)\left(d\right)$

2. Replace $n$ with the term you are looking for ( $141$ )

3. Replace $a_1$ with the first tern in the arithmetic sequence ( $15$ )

4. Say to yourself, this is why I was told to have a calculator ;)

5. The 141st term of the arithmetic sequence is
