Explanation

The sequence is a geometric progression with common ratio -1/2. -24 * (-1/2) = 12.

AI explanation

This is a geometric progression with a first term of 192 and a common ratio of -0.5, as each term is halved and its sign is reversed. Multiplying the fourth term (-24) by the common ratio (-0.5) gives (-24) * (-0.5) = 12. The next term is 12.
