Q. What is the next number of the following sequence
-12,6,-15,-5,28,-14,9,3,-18,___

• -12/-2=6
  -15/3=-5
  28/-2=14
  9/3=3
  -18/-2=9
  so, ans is 9

• 6*(-2)=-12,(-5)*3=-15,(-14)*(-2)=28,3*3=9
  so the series is -2,3,-2,3
  so the next 9*(-2)=-18.the next number is 9.

• Look upon the series carefully
  -12,6.....-15,-5......28,-14.....9,3.....-18,___
  
  -12/6 = -2
  -15/-5 = 3
  28/-14= -2
  9 / 3 = 3
  similarly
  -18/x = -2
  x = 9
  So ans will be 9

• -12,6,-15,-5,28,-14,9,3,-18,___
  -12/6 = -2
  -15/-5 = 3
  28/-14 = -2
  9/3 = 3
  -18/? = -2
  PUT THE VALUE OF ? IS 9
  SO -18/9 = -2
  SO ANS IS 9

• -12/6=-2
  -15/-5 = 3
  28/-14 = -2
  9/3 = 3
  -18/x = -2 ... x=9(ans)

• (-12,6)(-15,-5)(28,-14)(9,3)(-18,x)
  observe the pattern the right side value of each pair is 2,3 respectively of left side value..and the product of their sign are alternating i.e for first pair -,then +,-,+ so next would be -
  and x=would be 9 as 9*2=18.

• a,a/2,b,b/3......
  a=-18
  next will be (-18/2)= -9

• ans 9
  -12,(-12/-2),-15,(-15/3),28,(28/-2),9,(9/3),-18,(-18/-2)
