To find the indicated term of an arithmetic sequence given the first term ( a_1 = 12 ), the common difference ( d = -7 ), and the term number ( n = 22 ), you use the formula:
[ a_n = a_1 + (n - 1) \cdot d ]
Substitute the given values:
[ a_{22} = 12 + (22 - 1) \cdot (-7) ]
[ a_{22} = 12 + 21 \cdot (-7) ]
[ a_{22} = 12 - 147 ]
[ a_{22} = -135 ]
So, the 22nd term of the arithmetic sequence is ( a_{22} = -135 ).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
