Look at this series: $$32, 31, 33, 32, 34, 33,...$$. What is the next number?

A
34

B
32

C
35

D
36

Solution

The next number is $$35$$.
Here first $$1$$ is subtracted and then $$2$$ is added, and so on.
Question 2
1 / -0

Find the value of $$'?'$$ in the series: $$12, 17, 15, ?, 18, 23, 21,....$$

A
20

B
21

C
22

D
24

Solution

The series alternates the addition of $$5$$ with the subtraction of $$2$$.
So, the number is $$20$$.
Question 3
1 / -0

Choose the missing number in the series: $$2, 2, 3, 4, 4,$$__$$, 6, 6, 7, 8, 8, 9....$$

A
5

B
6

C
7

D
8

Solution

This is a continuous series of adding $$1$$ to the previous number, in which every third number is not repeated.
So, the missing number is $$5$$.
Question 4
1 / -0

Find the value of $$'x'$$ in the series: $$144, 169, x, 225, 256, 289$$.

A
190

B
192

C
196

D
195

Solution

The series is a perfect square in increasing order of $$12, 13, 14, 15...$$
So, the value of $$x$$ is $$196$$.
Question 5
1 / -0

Find the missing number in the pattern: $$2, 5, 8, 11,$$ __$$, 17, 20, 23, 26$$

A
11

B
12

C
13

D
14

Solution

The series adds $$3$$ to each number to get the next number.
So, the next number is $$11 + 3 = 14$$
Question 6
1 / -0

Which pair of numbers comes next?
$$25, 23, 5, 20, 16, 5,....$$

A
$$11, 5$$

B
$$5, 6$$

C
$$10, 5$$

D
$$9, 5$$

Solution

This is an alternating subtraction series with the interpolation of a random number, $$5$$, as every third number.
In the subtraction series, $$2$$ is subtracted, then $$3$$ then $$4$$, and so on.
The next pair of numbers are $$11$$ and $$5$$.
Question 7
1 / -0

Which number comes next?
$$5, 9, 13, 17, 21, 25, 29,...$$

A
$$31$$

B
$$32$$

C
$$30$$

D
$$33$$

Solution

The series adds $$4$$ to each number to get the next number.
So, the next number is $$29 + 4 = 33$$
Question 8
1 / -0

$$2, 3,$$ __$$, 4, 4, 5, 6, 6, 6, 7, 7, 7...$$ What number should fill the blank?

A
$$1$$

B
$$2$$

C
$$3$$

D
$$4$$

Solution
Question 9
1 / -0

Fill in the blank: $$62, 66, 63, 66, 64,$$ __$$, 65,....$$

A
60

B
61

C
62

D
63

Solution

The series alternates the addition of $$4$$ with the subtraction of $$3$$.
So, the missing number is $$61$$.
Question 10
1 / -0

Identify the missing integer: $$9, 45,$$ ____$$, 1125, 5625...$$

A
$$220$$

B
$$223$$

C
$$224$$

D
$$225$$

Solution

This is continuous series multiplied by $$5$$.
$$9 \times 5 = 45$$
$$45 \times 5 = 225$$
$$225 \times 5 = 1,125$$
$$1,125 \times 5= 5,625.$$
So, the missing integer is $$225$$.
