Here is an example problem for you to analyze: THIS IS HOW n + 2 ends up representing an odd number. What happens if you add 2 to an odd number? Try it!Īdding 2 to an odd number ALWAYS results in the next (consecutive) odd number. Loren suggested that you start by letting n = an odd integer. (The value of this expression, and, thus, the number it represents, depends SOLELY upon the value of n.) We're talking about a number represented by the expression: n + 2. Example, 4 + 5 = 9 –8 + (–7) = –15.You are correct when you say that 2 is an even number, but we're NOT TALKING ABOUT 2. The sum of any two consecutive numbers is always odd. So the explanation and examples above help you to understand about consecutive numbers, the word you might have heard in your day to day life too.Ĭuemath adds to the theory sets of integers, continuous whole numbers etc. The list actually is a pattern that makes us understand the concept of consecutive numbers in an efficient manner. This is the perfect example of consecutive numbers. The missing number in the consecutive number list is predecessor + difference Summing up Then find the difference between any predecessor-successor pair. Write the given numbers in order from the smallest to the largest. The term consecutive numbers is often used to frame word problems. N! Is “n factorial.” For a positive integer n, n! Is the product of all positive integers less than or equal to n.Įxample: 6! = 6 × 5 × 4 × 3 × 2 × 1 = 720 Overall, the product of n consecutive integers is divisible by n! If there is an even number of integers in a consecutive integer sequence, the product will always be divisible by 2.

In a sequence of consecutive numbers, the product will always be divisible by the number of integers. Divisibility Of Product Of Consecutive Integers We can also have consecutive even and odd integers.Įxample: Consecutive Even Integers: – 8, –6, –4, –2, 0, 2, 4, 6 ….Įxample: Consecutive Odd Integers: –9, –7, –5, –3, –1, 1, 3, 5, 7 …. Odd Consecutive Numbers Formula = 2n+1, 2n+3, 2n+5, 2n+7 … So, the sum of n consecutive numbers or sum of n terms of AP (Arithmetic Progression) = (n/2) × (first number + last number).Įven Consecutive Numbers Formula = 2n, 2n+2, 2n+4, 2n+6 … The formula for adding n consecutive numbers =. Given below are more consecutive number formulas. The difference between the predecessor and the successor of any number in a sequence is always the same.įor a number n, the next two consecutive numbers = (n + 1) and (n + 2).There will be accurately one number divisible by n in any set of n consecutive numbers.Depending upon the set which has been started there might be too even numbers and one odd number or vice versa in a set of three consecutive integers.If m is an odd number, then the total sum of m consecutive integers will be divisible by m.The difference between any two consecutive odd or even numbers is 2.These are called consecutive odd and even numbers because the difference between any predecessor-successor pair is 2. The list of ordinal number from 1 to 100 can be learned easily and is quite helpful for specifying the order of any given object Types of Consecutive NumbersĬonsecutive odd numbers The numbers are ordered as 1, 3, 5, 7, 9, 11, and 13 ……so on when written from the smallest to the largest are called consecutive odd numbers.Ĭonsecutive even numbers The numbers are ordered as 2, 4, 6, 8, 10, 12 ………so on when written from the smallest to the largest forms the list of consecutive even numbers. The difference between the preceding and succeeding numbers always is same.

For example if x is an integer 10 X + 1 and X + 2 are the consecutive integers.įrom the above examples we can see that the consecutive numbers follow a sequence. The may be a set of integers the mean and median where are equal. For example, if you write the numbers continuously starting from 1 and continue forward without breaking the sequence then the numbers are consecutive. Consecutive numbers can mean the numbers following continuously or in an unbroken sequence. Consecutive number, actually, are the numbers that follow each other in the ascending order, i.e., smallest to largest. In mathematics, every now and then we come across the word consecutive numbers.
