To find the 11th term of the sequence defined by the formula \( A_n = 4.8 + (n - 1) \), we simply need to substitute \( n = 11 \) into the formula.
\[ A_{11} = 4.8 + (11 - 1) \]
Calculating inside the parentheses:
\[ = 4.8 + 10 \]
Now, adding the numbers together:
\[ = 14.8 \]
So, the 11th term \( A_{11} \) is \( 14.8 \).
