Answer:
-142
Step-by-step explanation:
Recognize that each term is 7 less than the preceding term. Thus, this is an arithmetic function with common difference -7.
The formula for the nth term is a(n) = 19 - 7(n -1).
Here we want the 24th term. Substitute 24 for n in the above formula:
a(24) = 19 - 7(24 - 1) = 19 - 7(23) = -142
The 24th term is -142.
