Step 1. The sequence that we have is:

This is an arithmetic sequence and we need to find the 22nd term.
Step 2. The formula that defines an arithmetic sequence is:

where an is the value of the sequence for the nth term, a1 is the first term, and d is the difference between the terms.
In this case:

Step 3. Finding d, the difference between the terms:
Thus, the value of d is -4:

Step 4. Using the formula from step 2, we define a general equation for the sequence:

Using this equation, we can find any value of the sequence.
Step 5. Since we need to find the 22nd term, we take this value as the n value:

And substitute it into our equation:

Solving the operations:
