31. which pair of numbers comes next.
10 20 25 35 40 50 55
70 65
60 70
60 75
60 65
Answer: Option
Hints: This is an alternating addition series, in
which 10 is added, then 5, then 10, and
so on.
33. which pair of numberscomes next.
17 17 34 20 20 31 23
26 23
34 20
23 33
27 28
Answer: Option
Hints: This is an alternating subtraction series with
repetition. There are two different patterns
here. In the first, a number repeats itself;
then 3 is added to that number to arrive at
the next number, which also repeats. This
gives the series 17, 17, 20, 20, 23, and so on.
Every third number follows a second pattern,
in which 3 is subtracted from each
number to arrive at the next: 34, 31, 28.
34. which pair of numberscomes next.
2 3 4 5 6 4 8
9 10
4 8
10 4
9 4
Answer: Option D
Hints: This is an alternating addition series with a
random number, 4, interpolated as every
third number. In the main series, 1 is added,
then 2 is added, then 1, then 2, and so on.
35. which pair of numberscomes next.
61 57 50 61 43 36 61
29 61
27 20
31 61
22 15
Answer: Option
Hints: This is an alternating repetition series, in
which a random number, 61, is interpolated
as every third number into an otherwise
simple subtraction series. Starting with the
second number, 57, each number (except
61) is 7 less than the previous number.
37. which pair of numberscomes next.
8 22 12 16 22 20 24
28 32
28 22
22 28
32 36
Answer: Option C
Hints: This is an alternating repetition series, with a
random number, 22, interpolated as every
third number into an otherwise simple addition
series. In the addition series, 4 is added
to each number to arrive at the next number.
38. which pair of numberscomes next.
6 20 8 14 10 8 12
14 10
2 18
4 12
2 14
Answer: Option D
Hints: This is an alternating addition and subtraction
series. In the first pattern, 2 is added to
each number to arrive at the next; in the
alternate pattern, 6 is subtracted from each
number to arrive at the next.
40. which pair of numberscomes next.
8 11 21 15 18 21 22
25 18
25 21
25 29
24 21
Answer: Option B
Hints: This is an alternating addition series, with a
random number, 21, interpolated as every
third number. The addition series alternates
between adding 3 and adding 4. The number
21 appears after each number arrived at
by adding 3.
