To find the second term of the arithmetic sequence defined by the recursive formula:

To find the second term of the arithmetic sequence, we start with the information we have:

1. The first term is \( a_1 = 22 \).
2. The formula to find the next term is \( a_n = a_{n-1} - 10 \). This means to get the next term, we take the previous term and subtract 10 from it.

Now, let's find the second term, \( a_2 \):

Using the formula, we can write:

\[
a_2 = a_1 - 10
\]

Now, we plug in the value of the first term:

\[
a_2 = 22 - 10
\]

So when we do the subtraction:

\[
a_2 = 12
\]

That means the second term of the sequence, \( a_2 \), is \( 12 \).
