1.)-3,6,1,-2,4,-1,-1,2,-3,?
2.)-27,9,-3,81,-27,9,54,?
3.)4,6,2,12,18,14, ? ans::6

• 1) divide the series in the following way
  (-3,-2,-1)
  (6,4,2)
  (1,-1,-3)
  so the next number in the given series is 0 i.e
  -3+1=-2
  -2+1=-1
  -1+1=0

• 2)-27/-3=9
  9/-3=-3
  81/-3=-27
  -27/-3=9
  54/-3=-18
  Ans:-18

• please explain the 3rd series result

• 3) First element of a group i: 4*3^(i-1)
  Second element: 2*3^i
  Third element: 2*3^i - 4
  So next group (i =3) should be: {36, 54, 50}

• (-27,9,-3),(81,-27,9),(54,_,_)
  9*-3= -27
  -3*-3=9
  -27*-3=81
  9*-3=27
  18*3=54
  so,next term will be 18

• 1)-3,6,1,-2,4,-1,-1,2,-3
  Ans : 0
  Explanation :-3,6,1|-2,4,-1|-1,2,-3|?
  Need 1st term so -3,-2,-1,0
• 7 years agoHelpfull: Yes(2) No(0)
• 1) (-3,-2,-1,0)
  (6,4,2,0)
  (1,-1,-3,-5) ======>> so answer is 0 .
• 7 years agoHelpfull: Yes(1) No(2)
• 2.) -27,9,-3,81,-27,9,54,?
  9*-3=-27
  -27*-3=81
  so the answer is 6 by 9*6=54

• 1). alternatively take 3 numbers i.e (-3,-2,-1) in this we observe +1 series then next is our !!ans ( -1+1=0 )
  if we want further no also try similarly i.e.. (6,4,2) we see -2 pattern here then next is " 2-2=0 "
  similarly ( 1,-1,-3) here we see pattern is add -2 then next is " -3-2 = -5 ". so next series is (0,0,-5)

• 4*3=12
  6*3=18
  2*3=6
