**Here's the cool thing: We're NOT going to have to keep making these tables! Since all arithmetic sequences behave the same way (change by adding a number), we can get a formula that works for ALL of them!**

**Check out the pieces of our last guy:**

**Let's check to see if this thing works on another arithmetic sequence:**

**How about this guy?**

**This would be the formula:**

Let's use it to find | : |

**Now, let's check it the long way:**

**Yep!**

**The cool thing is that you can use this formula to find the 2000th term:**
