 These numbers relate to each other with some maths formula or mathematical operations or logical.

 One has to find this hidden relationship among these numbers and then solve it for the missing numbers.

 

51. Find the missing number

 

 

Answer  The pattern is:First row 51+30= 81 9^2=81 second row 24+40=64 8^2=64 third row 7^2=49 so 24 + ? =49 therefore 21 is the missing number. 

 

52. Find the missing number

 

 

  Answer  The pattern is:First row 28+8=36 6^2=36 second row 6+10=16 4^2=16 third row 75+25=100 ?^2=100 so the missing number is 10 10^2=100 

 

53. Find the missing number

 

  Answer  The pattern is:First row least common multiple LCM (6,8)=24 Second row least common multiple LCM (3,4)=12 Third row least common multiple LCM(6,4)=12

 

54. Find the missing number

 

  Answer  The pattern isFirst row 4=2^2 16=4^2 (2+4)^2=36 Second row 9=3^2 25=5^2 (3+5)^2=64 Third row 16=4^2 9=3^2 (4+3)^2=49:

 

55. Find the missing number.

 

  Answer  The pattern is:First row 42 4X2+(4+2)=14 14 1X4+(1+4)=4+5=9 Second row 62 6x2+(6+2)=12+8=20 20 (2X0)+(2+0)=2 Third row 28 (2X8)+(2+8)=16+10=26 26 (2X6)+(2+6)=12+8=20 

 

56. Find the missing number.

 

  Answer  The pattern is:First row LCM(4,16,8)=16 Second row LCM(9,18,6)=18 Third row LCM(24,6,8)=24 Fourth row LCM (12,3,9)=36

 

57. Find the missing number.

 

  Answer  The pattern is:16 (1+6)X3=21 21 (2+1)X3=9 09 (0+9)X3=27 So 18 (1+8)X3=9X3=27

58. Find the missing number. 

  Answer  The pattern is:12 (1+2)=3 3^2=9 9^2=81 81 (8+1)=9 9^2=81 So 169 (1+6+9)=16 16^2=256

 

59. Find the missing number

 

  Answer  The pattern isColumn AXB-C=D 8X4-16=32-16=16 5X7-18=35-18=17 3X7-7=21-7=14 9X3-13=27-13=14:

 

60. Find the missing number.

 

  Answer  The pattern is:Column ( A+B+C)/4=D (9+3+20)/4=32/4=8
