The sequence that shows a pattern where each term is 1.5 times the previous term is option D
Series of numbers can be in a sequence either in arithmetic or in geometric. In the above question, it is geometric because the sequence shows a pattern where each term is 1.5 times the previous term.
Let us test each option one by one.
Option A
1.5 x -4 = -6
But the next number in the series is 6
Option B
1.5 x 10 = 15
1.5 x 15 = 22.5
But the next number in the series is 25
Option C
1.5 x 98 = 147
But the next number in the series is 99.5
Option D
1.5 x -200 = -300
1.5 x -300 = -450
1.5 x -450 = -675
Therefore, the sequence that shows a pattern where each term is 1.5 times the previous term is option D
