 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.

 

 41. Find the missing number

Answer  The pattern is:In each row we consider 2 three-digit numbers. 144=12^2 064=4^3 169=13^2 125=5^3 196=14^2 216=6^3 225=15^2 343=7^3 256=16^2 512=8^3 289=17^2 72X=9^3=729 So X=9 

 

42. Find the missing number

 

 

Answer  The pattern is:In each row we consider 3 two-digit numbers. In each row we consider 2 two-digit numbers The middle number is the average of the other 2 numbers.45=(68+22)/2 50=(74+26)/2 So X= (68+92)/2=80.

 

43. Find the missing number.

 

 

Answer  The pattern is: 4X2+1=9 4X9+1=37 4X37+1=149 4X149+1=X So X=597

  44. Find the missing number

Answer  The pattern is:The sum of the numbers in each column is 36 So 10+10+8+4+X=36 X=4

 

45. Find the missing number.

 

 

 

 

Answer  The pattern is:If the numbers in a row are a, b, c then 9b=a+c 9X9=49+32 9X7=45+18 9X missing number=29+16=45 So 9X missing number-45 So missing number is 5

 

46. Find the missing number

 

 

Answer  The pattern is:If the numbers of a column are a, b, c, d then c=a^2-b^2 d=c^2-b^2 So 3^2-1^2=8 and 7^2-3^2=40

 

47. Find the missing number

   Answer  The pattern is:If the numbers in each figure are a, b, c then a^2+b^2=c 5^2+2^2=25+4=29 4^2+3^2=16+9=25 So X=4^2 +7^2=16 +49=65

 

48. Find the missing number

 

 

Answer  The pattern is:All numbers are perfect cubes.If the numbers of a row A,B,C,D The pattern is 3* cube base A *cube base B * cube base C=D First row 3* (2*3*4)=72 Second row 3*(1*2*3)=18 Third row 3*(5*6*2)=180

 

49. Find the missing number

 

 

Answer  The pattern is:The number in the center is the Greatest Common Divisor of the other numbers. GCD (16,32,48,24)=8 GCD (27,18,36,45)=9 GCD (36,54,18,24)=6

 

50. Find the missing number.

 

Answer  The pattern is: If the numbers of a row is A,B,C,D then A*C+B/2=D 3*5+6/2=18 So 5*4+6/2=23
