There are no real numbers that can do that job.

There's a pair of complex numbers that can do it.
They are

   5.5 + i4.97
and
   5.5 - i4.97 .

   ' i ' = the imaginary unit = √(-1)

Answer:

the right answer is $\frac{3}{4} ,-\frac{3}{5},- \frac{3}{6} ,-\frac{3}{7}$

Step-by-step explanation:

to find the reason for the sequence, the following formula must be used;

q = t2 / t1

where t2 is equal to the second value of the sequence and t1 to the first value.

q= t2/t1

q = $\frac{-\frac{3}{5} }{-\frac{3}{4} } = \frac{12}{15} =\frac{4}{5}$

$a^{-1} = \frac{1}{a}$
