• 1)Right question will be 8,5,9,7,2,25,5,1,16,8,6,?
  (8,5,9),(7,2,25),(5,1,16),(8,6,x)
  
  (a,b,c) => (a-b)^2 = c
  
  (8 - 5)^2 = 9
  (7 - 2)^2 = 25
  (5-1)^2 = 16
  => (8 - 6)^2 = x => x = 4
  
  2)Right series will be 1.25,3,7.1,1.50,1,8.1,1.75,-1,9.1,2.00,?
  1.25+0.25=1.50 , 1.50+0.25=1.75 , 1.75+0.5=2.00
  3-2=1 , 1-2=-1 ,-1-2=-3
  7.1+1=8.1 , 8.1+1= 9.1 , 9.1+1=10.1
  3 series are there...Answer will be -3 (from 2nd series).
  
  3)Right series will be..7,4,6,3,4.5,1.5,2.25,-0.75,?
  7-3=4; 4*(3/2)=6 ;
  6-3=3; 3*(3/2)=4.5;
  4.5-3=1.5; 1.5*(3/2)=2.25;
  2.25-3=-0.75; -0.75*(3/2)= -1.125
  Ans: -1.125

• 2)Right series is 1.25, 3, 7.1, 1.50, 1, 8.1 ,1.75, -1, 9.1, 2.00,?
  
  three alternate patterns are there in this series.. write it in matrix form
  1.25 1.50 1.75 2.00 ( addition of 0.25 each )
  3 1 -1 ? (subtraction -2 from each )
  7.1 8.1 9.1 ? (addition of 1 each)
  
  so ans : -3 and 10.1
