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.

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

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
