To find the second term of the arithmetic sequence given the recursive formula, we start with the initial term \( a_1 \) and use the formula to compute \( a_2 \).

Given:

  • \( a_1 = 22 \)
  • \( a_n = a_{n-1} - 10 \)

We can find \( a_2 \) using the recursive formula:

\[ a_2 = a_1 - 10 \] \[ a_2 = 22 - 10 \] \[ a_2 = 12 \]

Thus, the second term \( a_2 \) of the sequence is:

\[ \boxed{12} \]
