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
