# Week 17 – Math 10

This week in math 10, we learned Arithmetic Sequences. An arithmetic sequence is a list of numbers with a definite pattern.

Let’s say we have to determine $t_n$ and $t_30$

We can know that d is 2. And then, we can figure $t_n$ out using it.

After that, we can find $t_30$ using $t_n$ =$t_1$+(n-1)(d)

We should put 10 in $t_n$, 30 in n and, -2 in d.

Now, we can get $t_30$= 10+(30-1)(-2) and, $t_30$=48
