If the fourth term in a geometric sequence is - 1 and the common ratio is -1, find the explicit formula of the sequence.
A)
an = (1) - (1)n- 1 for n 2 2
B)
an = (1) · (–1)n- 1 for n 2 1
C) an = (– 1) - (1)n - 1 for n 2 1
D) an = (-1) - (-1)" - 1 for n< 1

hop

x = 17

step-by-step explanation:

1st step: isolate x.

24 - 3x = -27

-24         -24

-3x   =   -51

2nd step: divide.

-3x     =   -51

  3             3

  x       =     17

hope this
