Numbers written consecutively according to a certain rule are called sequential numbers.

**1) Consecutive Integers**

Successive integers such as ……… -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5 ……… are called consecutive integers. The difference between these numbers is 1.

⇒ If we want to formulate consecutive integers, we can express them with symbols such as n, n+1, n+2, n+3, n+4.

**2) Consecutive Even Integers**

Consecutive numbers such as …….. -6, -4, -2, 0, 2, 4, 6 ……….. are called consecutive even integers. The difference between consecutive even integers is 2.

⇒ If we want to formulate consecutive even integers, we can express them with symbols such as n, n+2, n+4, n+6, n+8.

**3) Consecutive Odd Integers**

Odd numbers in the form of ……… -7, -5, -3, -1, 1, 3, 5, 7 ……….. are called sequential integers. The difference between consecutive odd integers is again 2.

⇒ If we want to formulate consecutive odd integers, we can express them with symbols such as n, n+2, n+4, n+6, n+8.

⇔ The ”n” expressions shown here should be chosen as odd or even, depending on which one is formulated in consecutive even and consecutive odd integers. These symbolized formulas look the same but express different (odd or even) numbers.

Consecutive numbers appear in different ways in kpss general aptitude math questions. Examples of kpss questions about consecutive numbers are as follows.

Consecutive integers in the form of 3n+4 and 4n-2 are given and the values that n can take are asked.

kpss questions asked by ordering a < b < c and giving consecutive numbers.

It is said that the sum of x consecutive integers is and it is asked what is the smallest or largest of these numbers.

**Arithmetic Sequence Sum**

A series of numbers whose sum of arithmetic sequences has a constant difference between consecutive terms is called an arithmetic sequence.

⇒ The difference between the arithmetic terms is called the common difference.

Arithmetic sequences can be odd and even, as well as odd even mixed numbers.

5, 10, 15, 20, 25, 30 ….. Common difference 5.

8, 16, 24, 32, 40, 48 ….. Common difference 8

7, 14, 21, 28, 35, 42 ….. Common difference 7
