What does the expression diploid 2n number mean to you?
Every number multiplied by 2 is an even number, so that 2n is an even number. Usually we represent an even number by 2n.
Why does an even number plus to odd number equal to odd?
Any even number can be written in the form 2n for some natural number n.Any odd number can be written as 2n+1 for a natural number nNow add an even to an odd.2n+2n+1=4n+1 which is 2(2n)+1 and this is the form for an odd number.
The product of an odd and an even number always odd?
odd x even = even (2n + 1)(2n) = 2[n(2n + 1)] let n(2n + 1) = t = 2t (even)
Is the sum of 2 numbers can be odd then there product is odd as well?
Let's take a look at this. For any integer n, 2n always be even, then the next consecutive number 2n + 1 must be odd. Let add them first, 2n + 2n + 1 = 4n + 1 = 2(2n) + 1 So their sum is odd, since every even number multiplied by 2 is also even. Let's multiplied them, 2n(2n + 1) = (2n)^2 + 2n Their product is even, since every even number raised in the second power is also even, and the sum of two even numbers is even too. So the answer is that when the sum of two numbers can be odd, their product is an even number. (note that the sum of two odd numbers is even)
What are the consecutive even number?
They are numbers of the form 2n and 2n+2 where n is any integer.
When odd even numbers are added will the answer be odd or even?
Suppose N stands for any number. Then 2N will always be even, so 2N + 1 will always be odd. Now let K stand for any other number. Then 2K + 1 will be another odd number. Now suppose we add these two odd numbers ; 2N + 1 + 2K + 1 = 2N + 2K +2 Factor out a 2, 2(K + N + 1) So the result of adding two odd numbers always gives a number which has the factor 2. So it is always an even number. Now add an even number 2N with an odd number 2K + 1 to get; 2N + 2K +1 . Since 2N + 2K is always an even number (has the factor 2 ) then 2N + 2K + 1 will always be an odd number.
If two odd numbers are added together what is the result?
Two odd numbers added together will always be an even number. I'll show how: Let M and N be any two integers. 2M is even, and 2N is even. So (2M +1) is an odd number, and (2N + 1) is an odd number. (2M +1) + (2N +1) = 2M + 1 + 2N +1 = 2M + 2N + 2 = 2(M + N + 1), which is even.
En is an even-number function Find E7 when En 2n?
The twelfth even number and 24.

The nth even number is 2n...
Why do you get an even number when adding two even numbers together?
The presentation of an even number is 2n (we can use any letter, such as 2m or 2r) Let the first even number be 2n and the second number be 2m. So we have, 2n + 2m = 2(n + m) let n + m = r, then by substituting r for n + m we have = 2r Since 2r represents an even number, then we can say that when are adding two even numbers we obtain another even number.
Is the sum of an even whole number and an odd whole number always odd?
Yes --------------------------------------------- Let n be an integer. Then 2n is an even number Let m be an integer. Then 2m is an even number and 2m + 1 is an odd number. Then: even + odd = (2n) + (2m + 1) = (2n + 2m) + 1 = 2(n + m) + 1 = 2k + 1 (where k = m + n) which is an odd number.
What is the product of two even numbers?
The product of two even numbers is always an even number.Here is the proof:We define an even number as a number of the form 2n for some integer n.Now let 2n be one even number and 2m be another.The product is (2n)(2m)=2(2mn) and of course 2mn is an integer since the integers are closed under multiplication. Hence, 2(2mn) is an even number.
