![## Determine the Explicit Formula for the Following Sequences
**4. Sequence:**
\[
\frac{1}{2}, \frac{5}{6}, \frac{7}{6}, \frac{3}{2}, \frac{11}{6}, \ldots
\]
- **Starting Term (\(a_1\)):** \(\frac{1}{2}\)
- **Common Difference (\(d\)):** \(\frac{1}{3}\)
**Explicit Formula:**
\[
a_n = a_1 + (n-1) \cdot d
\]
Substitute \(a_1 = \frac{1}{2}\) and \(d = \frac{1}{3}\) into the formula to determine \(a_n\).](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fc41b3e59-056b-4506-b9f6-b043ec3b5013%2F32d961bc-8edb-4f21-ad9c-0a507e673047%2F3tpksd_processed.png&w=3840&q=75)
