• 5) 18,24,5,21,27,8,17,23,4,24,30,?
  Ans. We divide the series into 3 terms each
  the 1st term will be 18,24,5
  so we get it by (24-18)=6 and (24-5) = 19
  similarly when we reach the last number which is 30 we subtract 19 from it we get 11(ans)
• 9 years agoHelpfull: Yes(17) No(7)
• 6) Ans:0
  Divide The Series in 3 segment
  -3,6,1 -2,4,-1 -1,2,-3, ???
  So every starting no decrease by -1 so the 4th segment started with 0

• 3)The right question will be 0,1,2,0.5,2,2,2,2,4,3,2,?
  
  Ans. We divide it into 4 terms.
  the 1st is 0,1,2,0.5
  we get it be (0+1)/2=0.5
  the 2nd is 2,2,2,2
  we get it by (2+2)/2=2
  the 3rd is 4,3,2
  we get it by (4+3)/2 =3.5 (Ans)

• 4) ans = 0,1,2,0,0.5,2,2,2,2,4,3,2,2,2,4.5
  take series into parts
  (0,1,2,0,0.5)
  0+1 = 1/2 = 0.5+0 = 0.5
  (2,2,2,2,4)
  2+2 = 4/2 = 2+2 = 4
  (3,2,x,y,z)
  3+2 = 5/2 = 2.5+2 = 4.5
  so x= 2, y= 2, z= 4.5

• 10) divide series in groups of three ( first term is multiplied by 2 and last term is divided by -2)
  (-16,-8,4)-8X2= -16 & -8/-2=4
  24,12,-6 = 12X 2 and 12/-2
  similarly -40 is twice the required term
  So ans is -20

• 2) the correct question is 7,4,6,3,4.5,1.5,2.25, ?
  
  explanation is :
  
  7-4=3 , 6-3=3, 4.5-1.5=3, 2.25-x=3,
  
  so x= -0.75
  
  and the next term is comin like previous term*1.5
  
  so next term will be -0.75*1.5= - 1.125

• 8) The right question will be 3,2,1,4,5,4,5,1,0,6,3,?
  Ans. We first take the terms 3,4,5,6
  Each is having a difference of 1
  Again 3,2 4,5 1,0 is having difference of 1
  so the ans is 2
