The nth term of a sequence is (2n-3), find its fifteenth term.

Answer

To find the fifteenth term of the sequence defined by the nth term \( a_n = 2n - 3 \), we can follow these steps:

### Step 1: Identify the formula for the nth term
The nth term of the sequence is given by:
\[ a_n = 2n - 3 \]

### Step 2: Substitute \( n = 15 \) into the formula
To find the fifteenth term, we substitute \( n = 15 \) into the formula:
\[ a_{15} = 2(15) - 3 \]

### Step 3: Calculate the value
Now, we perform the calculation:
\[ a_{15} = 30 - 3 \]
\[ a_{15} = 27 \]

### Final Answer
The fifteenth term of the sequence is:
\[ \boxed{27} \]
