Answer:
- 768 , 3072 , - 12288
Explanation:
there is a common ratio between consecutive terms , that is
- 12 ÷ 3 = - 4
48 ÷ - 12 = - 4
- 192 ÷ 48 = - 4
to obtain the next term in the sequence multiply the preceding term by - 4
- 192 × - 4 = - 768
- 768 × - 4 = 3072
3072 × - 4 = - 12288
the next three terms are - 768 , 3072 , - 12288
