## Successor and Predecessor

**Successor**: A **successor** is a number that comes immediately after another number in a sequence. In mathematics, if you have a number n, its successor is n+1.

**Predecessor**: A **predecessor** is a number that comes immediately before another number in a sequence. In mathematics, if you have a number n, its predecessor is nβ1.

### Examples of Successors and Predecessors

#### Successors

- The successor of 5 is 6.
- The successor of 10 is 11.
- The successor of 0 is 1.

#### Predecessors

- The predecessor of 5 is 4.
- The predecessor of 10 is 9.
- The predecessor of 0 is -1.

## Consecutive Even Numbers

**Consecutive Even Numbers**: Consecutive even numbers are even numbers that follow each other in order. The difference between each pair of consecutive even numbers is 2. For example, the sequence 2, 4, 6, 8 consists of consecutive even numbers.

### Identifying Consecutive Even Numbers

To identify consecutive even numbers, start with any even number and keep adding 2 to find the next even number in the sequence.

### Examples of Consecutive Even Numbers

- Starting from 2: 2, 4, 6, 8, 10
- Starting from 10: 10, 12, 14, 16, 18
- Starting from -4: -4, -2, 0, 2, 4

### Properties of Consecutive Even Numbers

**Evenness**: All numbers in the sequence are divisible by 2.**Equal Differences**: The difference between any two consecutive numbers in the sequence is always 2.**Arithmetic Progression**: Consecutive even numbers form an arithmetic sequence where the common difference (d) is 2.

### Formula for Consecutive Even Numbers

If you want to find the n-th consecutive even number starting from a given even number aaa, you can use the formula:

n-th even number=a+2(nβ1)

**Example**: To find the 5th consecutive even number starting from 6:

5th even number=6+2(5β1)=6+2Γ4=6+8=14

## Consecutive Odd Numbers

Consecutive odd numbers are odd numbers that follow each other in order. The difference between each pair of consecutive odd numbers is 2. For example, the sequence 1, 3, 5, 7 consists of consecutive odd numbers.

### Identifying Consecutive Odd Numbers

To identify consecutive odd numbers, start with any odd number and keep adding 2 to find the next odd number in the sequence.

### Examples of Consecutive Odd Numbers

- Starting from 1: 1, 3, 5, 7, 9
- Starting from 11: 11, 13, 15, 17, 19
- Starting from -5: -5, -3, -1, 1, 3

### Properties of Consecutive Odd Numbers

**Oddness**: All numbers in the sequence are not divisible by 2.**Equal Differences**: The difference between any two consecutive numbers in the sequence is always 2.**Arithmetic Progression**: Consecutive odd numbers form an arithmetic sequence where the common difference (d) is 2.

### Formula for Consecutive Odd Numbers

If you want to find the n-th consecutive odd number starting from a given odd number aaa, you can use the formula:

n-thΒ oddΒ number=a+2(nβ1)

**Example**: To find the 5th consecutive odd number starting from 7:

5th odd number=7+2(5β1)=7+2Γ4=7+8=15\text{5th odd number} = 7 + 2(5-1) = 7 + 2 \times 4 = 7 + 8 = 155th odd number=7+2(5β1)=7+2Γ4=7+8=15

### Real-Life Applications

Consecutive odd numbers appear in various real-life contexts:

**Seating Arrangements**: Odd-numbered seats in theaters or stadiums.**House Numbers**: Houses on one side of a street often have odd numbers.**Batch Numbers**: Items produced in consecutive odd-numbered batches.

### Exercises for Practice

- Write the next five consecutive odd numbers starting from 9.

**Answer**: 9, 11, 13, 15, 17, 19

- Find the 6th consecutive odd number starting from 3.

**Answer**: 6th odd number=3+2(6β1)=3+2Γ5=3+10=13

- Identify the consecutive odd numbers between -9 and 9.

**Answer**: -9, -7, -5, -3, -1, 1, 3, 5, 7, 9

## Properties of Consecutive Numbers

Consecutive numbers are a sequence of numbers where each number is one more than the previous number. Understanding their properties helps in solving various mathematical problems efficiently. Here are some key properties:

**Consecutive Numbers**: A series of numbers where each number is one more than the previous number. For example, 3, 4, 5, 6 are consecutive numbers.

### Difference Between Consecutive Numbers

- The difference between any two consecutive numbers is always 1.
- Example: 7β6=1

### Sum of Consecutive Numbers

- The sum of n consecutive numbers can be calculated using the formula:
- Sum=n/2Γ(First Number+Last Number)
- Example: Sum of 1, 2, 3, 4, 5 is: Sum=5/2

### Average of Consecutive Numbers

- The average of n consecutive numbers is the same as the middle number if n is odd, or the average of the two middle numbers if n is even.
- Example: Average of 1, 2, 3, 4, 5 is:
- Average=1+2+3+4+55=3\text{Average} = \frac{1+2+3+4+5}{5} = 3Average=51+2+3+4+5β=3

### Product of Consecutive Numbers

- The product of n consecutive numbers grows rapidly and can be calculated using factorial notation when starting from 1.
- Example: Product of 1, 2, 3, 4 is: 1Γ2Γ3Γ4=24(or 4!)

### Properties of Odd and Even Consecutive Numbers

**Odd Consecutive Numbers**: A sequence of numbers where each number is an odd number (e.g., 1, 3, 5, 7).- The difference between two odd consecutive numbers is always 2.

**Even Consecutive Numbers**: A sequence of numbers where each number is an even number (e.g., 2, 4, 6, 8).- The difference between two even consecutive numbers is always 2.

## Consecutive Numbers Formula

## FAQs

## What are consecutive numbers 1 to 100?

Consecutive numbers from 1 to 100 are numbers that follow each other in order without gaps. Starting from 1, they increase by 1 each time, ending at 100.
