A11 =

Answer 1

To find the 11th term of the arithmetic sequence given the explicit formula \( A_n = 4.8 + (n - 1) \cdot 2 \), we simply substitute \( n = 11 \) into the formula.

\[ A_{11} = 4.8 + (11 - 1) \cdot 2 \] \[ A_{11} = 4.8 + 10 \cdot 2 \] \[ A_{11} = 4.8 + 20 \] \[ A_{11} = 24.8 \]

Thus, the 11th term \( A_{11} \) is \( \boxed{24.8} \).
