# Number Series Solved MCQs

A Number Series is a sequence of numbers that follow a specific rule or set of rules These series can be found in mathematical sequences, geometric shapes, and other areas of mathematics and science. Different types of number series include Addition Series, Subtraction Series, Multiplication Series, Division Series, Square Number Series, Cube Number Series, Fibonacci Numbers Series, Prime Numbers Series, and more Each type of series follows a unique rule for generating the numbers in the series.
Instructions

1. Analyze the sequence of numbers given in the series.
2. Look for any patterns or relationships between consecutive numbers.
3. Extend the pattern to predict the next number in the series.
4. Verify your prediction by applying the identified pattern to the subsequent numbers.

1.

## What number should come next in the series? 1, 1, 2, 3, 5, 8, 13

A. 15
B. 17
C. 18
D. 21
Explanation: This is a classic example of a Fibonacci series, where each number is the sum of the two preceding ones. So the next number should be 8 (the last number in the series) + 13 (the second last number in the series) = 21.
2.

## What number should come next in the series? 2, 3, 5, 7, 11

A. 12
B. 13
C. 17
D. 19
Explanation: This is a series of prime numbers, which are numbers that have only two distinct positive divisors: 1 and the number itself. The next prime number after 11 is 13.
3.

## What number should come next in the series? 1, 4, 9, 16

A. 20
B. 25
C. 30
D. 36
Explanation: This is a series of perfect squares. The next perfect square after 16 (which is 4 squared) is 25 (which is 5 squared).
4.

## What number should come next in the series? 2, 4, 8, 16

A. 18
B. 20
C. 24
D. 32
Explanation: This is a series where each number is the double of the previous number. So the next number should be 16 (the last number in the series) * 2 = 32.
5.

## What number should come next in the series? 5, 10, 20, 40

A. 80
B. 85
C. 90
D. 95
Explanation: This is a series where each number is the double of the previous number. So the next number should be 40 (the last number in the series) * 2 = 80.
6.

## What number should come next in the series? 3, 6, 12, 24

A. 36
B. 40
C. 45
D. 48
Explanation: This is a series where each number is the double of the previous number. So the next number should be 24 (the last number in the series) * 2 = 48.
7.

## What number should come next in the series? 5, 10, 17, 26

A. 34
B. 35
C. 37
D. 39
Explanation: This is a series where each number is one less than the square of a natural number. So the next number should be $$6^2 - 1 = 35$$.
8.

## What number should come next in the series? 1, 8, 27, 64

A. 100
B. 125
C. 144
D. 169
Explanation: This is a series of cubes of natural numbers. The next cube after $$4^3 = 64$$ is $$5^3 = 125$$.
9.

## What number should come next in the series? 2, 6, 12, 20

A. 30
B. 32
C. 34
D. 36
Explanation: This is a series where each number is two times the corresponding triangular number. So the next number should be $$2 * 6 * (6 + 1) / 2 = 30$$.
10.

## What number should come next in the series? 5, 11, 23, 47

A. 80
B. 90
C. 95
D. 100
Explanation: This is a series where each number is one less than double the previous number. So the next number should be 2*47 - 1 = 95.
11.

## What number should come next in the series? 1, 8, 27, 64, 125

A. 200
B. 216
C. 225
D. 256
Explanation: This is a series of cubes of natural numbers. The next cube after $$5^3 = 125$$ is $$6^3 = 216$$.
12.

A. 162
B. 170
C. 180
D. 190
