## 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 \(a_n\).
