What is the name given to all the numbers that can be expressed as the sum of two consecutive whole numbers?
Odd. For any given whole number n, the sum of it and the next whole number is 2n+1. Since 2n is obviously a multiple of 2 and therefore even, 2n+1 must be odd.
What is difference between the n and 2n number?
2n is 2 times n.
How do you get 9 from 2n plus 4?
'n' can be any number, but when applied to (2n + 4), n = 2.5
E n is an even-number function Find E9 when En equals 2n?
If n = 9 then 2n must be 18.
What are the consecutive even number?
They are numbers of the form 2n and 2n+2 where n is any integer.
Is 2n a whole number?
The answer depends on n. If n is an integer or half on integer then 2n is a whole number; if not, then it isn't.
A sum of a number and twice its number?
If the number is n, then twice the number is 2n and the sum of the two is n + 2n = 3n.
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.
Twice what number is equal to three times that number?
let the number be n. Then: 2n = 3n ⇒ 2n - 2n = 3n - 2n ⇒ 0 = n ie, the number is zero.
What is the name given to all the numbers that can be expressed as the sum of two consecutive whole numbers?

What is difference between the n and 2n number?
2n is 2 times n.
The sum of 2 consecutive whole numbers is 97 what are the 2 numbers?
Okay, so two consecutive numbers are basically (n) and (n + 1).now:97 = n + (n+1)97 = 2n + 1- 1 -196 = 2n/2 /2n = 96/2n = 48We said that the first number is (n) and the second number is (n + 1), that means that the numbers are 48 and 49.
What is the greatest whole number that MUST be a factor of the sum of any six consecutive positive odd numbers?
Let the first odd number be 2n-5 (n ≥ 3), then the 6 consecutive odd numbers are: 2n-5, 2n-3, 2n-1, 2n+1, 2n+3, 2n+5 And their sum is: 2n-5 + 2n-3 + 2n-1 + 2n+1 + 2n+3 + 2n+5 = 12n The greatest common factor for all n(≥ 3) of 12n is 12. Thus 12 is the greatest whole number that MUST be a factor of the sum of any six consecutive positive odd numbers.
How do you get 9 from 2n plus 4?
'n' can be any number, but when applied to (2n + 4), n = 2.5
What is true of meiosis n to n n to 2n 2n to n or 2n to 2n?
it is 2n -n because in meiosis a diploid 2n becomes a haploid n.
Five less than twice a number is 7?
If the number is N then 2N - 5 = 7 then 2N = 12 so that N = 6
What expression represents twice a number n plus three?
twice a number n is 2n plus 3 is + 3 → twice a number n plus 3 is 2n + 3.
