• 1)1*3=3
  2+8=10
  3*4=12
  ans:4
  2)6^5=7776
  5^4=625
  4^3=64
  3^2=9
  ans:2^1=2
  3)7*(-2)=-14
  15*(-2)=-30
  ans:(-21)* (-2)=42
  4)7*(-5)=-35
  (-3)*(-5)=15
  ordering like this -35,15,?
  next no must be 65
  so,65/(-5)=-13:ans
  5)it is of sequence -2,+2,*2
  so,ans:14
  6)3+7=10
  8+4=12
  ......
  ans:3+2=5
  7)3(2,1) 4(5,4) 5(1,0) 6(3,2)
  ans:7
  8)169*3=507
  62*4=248
  ........
  168/3=56:ans
  9)1*1+1=2
  2*2-1=3
  3*3+1=10
  ...........
  ans:63
  10)7-4=3,4*1.5=6
  6-3=3,3*1.5=4.5
  4.5-3=1.5,1.5*1.5=2.25
  ans:2.25-3=-.75
  11)3.2*5=16
  12*5=60

  3,4,12
  4 ans.
  
  6) 3+7=10
  8+4=12
  0+5=5
  3+2=5 ans
  
  4) 7*-5=-35 -3*-5=15
  -35+1=-34 15+1=16
  
  (-3)-7=-10
  so -3-10=-13 ans
  
  7) there are set of 3 nos.
  
  (3,2,1)
  (4,5,4)
  (5,1,0)
  (6,3,2)
