To find the 15th term in the sequence defined by the formula \( c_n = 3n - 1 \), we need to substitute \( n = 15 \) into the formula.
\[
c_{15} = 3(15) - 1
\]
Calculate this step-by-step:
1. Multiply \( 3 \) by \( 15 \):
\[
3 \times 15 = 45
\]
2. Subtract \( 1 \):
\[
45 - 1 = 44
\]
Thus, the 15th term \( c_{15} \) is \( 44 \).
The answer is: **44**.
\[
c_{15} = 3(15) - 1
\]
