In the given geometric series, each next term is obtained by multiplying the previous term by a fixed number known as common ratio.

In this case the common ratio is -3.

As,

- 3.49 x -3 = 10.47
10.47 x - 3 = -31.41
and so on...

So, the next number of the series will be: 

94.23 x - 3= -282.69

Thus, the answer to this question is - 282.69
