To find the second term \( a_2 \) of the arithmetic sequence given by the recursive formula:
- The first term is provided as \( a_1 = 22 \).
- The recursive formula is \( a_n = a_{n-1} - 10 \).
Using this formula to find \( a_2 \):
\[ a_2 = a_1 - 10 \] Substituting the value of \( a_1 \):
\[ a_2 = 22 - 10 = 12 \]
Therefore, the second term \( a_2 \) is \( 12 \).
So the correct response is:
a2=12
