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
