Practice questions number series

81. Find the missing number

Answer  The pattern is: 68+9=77 77+18=95 95+ 27=122 So 122+36=158

 

82. Find the missing number

 

 

 

 

 

  Answer  The pattern is:This is an alternating multiplication and subtracting series: First, multiply by 2 and then subtract 8. Correct answer is 16

83. Find the missing number

 

 

 

  Answer  The pattern is:Two independent series This is an alternating addition and subtraction series. In the first pattern, 10 is subtracted from each number to arrive at the next. In the second, 5 is added to each number to arrive at the next. Correct answer is 20

 

84. Find the missing number

 

 

  Answer  The pattern is:In this alternating repetition series, a random number, 15, is interpolated every third number into a simple addition series, in which each number increases by 3. Correct answer is 23,15

 

85. Find the missing number

 

 

 

 

 

  Answer  The pattern is:This is an alternation multiplication and addition series. First we multiple by 2 to go to the next term and then add 3 to go to the next term 8x2=16 16+3=19 19x2=38 38+3=41 41x2=82 82+3=85 85x2=170 Correct answer is 85,170

 

86. Find the missing number

 

 

 

  Answer  The pattern is:The divisors of the numbers in the given series are : 1, 4, 9, ?, 25, 36 *(3/36=1/12) All the numbers are perfect squares of 1, 2, 3, ? ,5, 6 The missing number is 4 4²=16 So 3/16 is the number will replace the question mark in the given series 

 

87. Find the missing number

 

 

 

  Answer  The pattern is:2 2x2+1=5 5 5x2+2=12 12 12x2+3=27 27 27x2+4 =58 58 58x2+5=121

 

88. Find the missing number

 

 

 

  Answer  The pattern is:5+1+1²=7 7+2+2²=13 13+3+3²25 25+4+4² =45 45+5+5² = 75

 

89. Find the missing number

 

  Answer  The pattern is:The differences of the terms are: 888-672=216 216=6³ 672-547=125 125=5³ 547-483=64 64=4³ 483-456=27 27=3³ Therefore the next term is 456-2³=456-8=444 

 

90. Find the missing number

 

  Answer  The pattern is:16x1-2=14 14x2-4=24 24x3-8=64 64x4-16=240 240x5-32=1168
