What is the 24th term of 19, 12, 5, - 2?

-7 each time. answer - 149

-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.
