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

First we are going to start with a equation 10,8,6

Let’s say we have to determine and

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

After that, we can find using =+(n-1)(d)

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

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