\r
The first term of an arithmetic sequence is 5. The third term is 13. Which of the following expressions represents the nth term of the sequence?\r
\r
We’ll start by breaking down what we know about arithmetic sequences — how each term increases by a common difference — and use that to find a formula that works for any term in the sequence.\r
\r
You’ll learn how to:\r
✅ Identify the first term (a₁) and the common difference (d)\r
✅ Use the formula aₙ = a₁ + (n - 1)d\r
✅ Write a general expression for the nth term\r
✅ Check your result with the given sequence\r
\r
We’ll also discuss how this connects to Common Core Standard HS.F-LE.A.1, which focuses on building linear models and recognizing patterns that increase by equal differences over equal intervals.\r
\r
By the end of the video, you’ll know exactly how to write and interpret arithmetic sequence formulas — and how they relate to linear functions!\n
