# How do you prove the product of two consecutive even numbers?

## How do you prove the product of two consecutive even numbers?

=k⇒n(n+1)=2k. Hence the product of two consecutive integers is divisible by 2. Hence the product of two consecutive integers is even. Hence any integer is of one of the form 2q, 2q+1.

Is the product of two consecutive numbers even?

Since the product of an even number and an odd number is always even, the product of two consecutive numbers (and, in fact, of any number of consecutive numbers) is always even.

Had of two consecutive numbers is always?

The HCF o two consecutive numbers is always one. The reason behind this is that the two consecutive numbers do not have any common factor other than 1. Hence 1 becomes the highest common factor between two consecutive numbers.

### What is the product of two consecutive natural number?

The product of two consecutive natural numbers is n(n+1). This product is an even number if it has 2 as one of the factors otherwise it is an odd number. If the product is divisible by one 1 and number itself then it is a prime number.

Is it true that product of 3 consecutive natural numbers is always divisible by 6 Justify?

Yes. If you have 3 consecutive natural numbers, then at least 1 of them must be divisible by 2, and 1 of them must be divisible by 3. Thus their product must always be divisible by 2×3=6.

What are the two consecutive numbers?

Consecutive numbers meaning is “The numbers which continuously follow each other in the order from smallest to largest.” Consecutive numbers from 1 to 8 are 1, 2, 3, 4, 5, 6, 7, 8. Here the difference between each number is 1. Consecutive numbers from 80 to 90 with difference as 2 are 80, 82, 84, 86, 88, 90.

## What is the difference between any two consecutive multiples of 3?

Two consecutive multiples of 3 can be written as 3k and 3k+3 where k is an integer. Clearly, 3 is a common factor of these two numbers , which means that HCF, being the highest common factor, is at least 3 i.e. Theorem: HCF of two positive integers a and b can be written as ma+nb where m and n are some integers.

Why the product of any three consecutive whole numbers is divisible by 6?

The answers 6, 24, 60 are all divisible by 6, because each product has an even number and a multiple of 3. The answer will always be divisible by 6 because in each of the products there will always be a multiple of 2 and 3. A multiple of 3 happens every three times.

How to prove the product of two consecutive numbers?

Define a second number p such that p := n + 1 = 2 k + 1 this ensures that p is an odd number and the numbers n and p are consecutive because they differ by 1. There product is given by: Which is clearly a multiple of 2.

### How to prove that two natural numbers are even?

Prove that the product of two consecutive natural numbers is even. 2. The attempt at a solution Hi, I’m just starting to work with proofs by induction, I’m just wondering if this is a valid technique, and/or if I am being too verbose in my proof, thanks!

What is the product of two even numbers?

The product of two consecutive even numbers is 3248. Actually, I am interested in finding the larger number out of the two. Say one of the even numbers is a and the consecutive even number is a + 2, then a(a + 2) = 3248, so we can get the larger number by finding the roots of the above quadratic equation.

How to prove the product of four positive integers?

Select any a ∈ Z ≥ 2 and define P to be the product of the four consecutive integers a − 1, a, a + 1 and a + 2, that is P = (a − 1)a(a + 1)(a + 2). Expanding P, we get P = a4 + 2a3 − a2 − 2a. Thus, we have P + 1 = a4 + 2a3 − a2 − 2a + 1 = (a2 + a − 1)2, that is P + 1 is a perfect square.
