Use the explicit formula An = 4.8 + (n - 1) 2 to find the 11th term in the described

Question

arithmetic sequence.

Answer 1

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

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

Therefore, the 11th term of the sequence is \( A_{11} = 24.8 \).
