Any odd number greater than 1 can be written in the form 2n + 1 where n = 1,2,3,...
then 2n+1 = (n + 1)2 - n2
Any multiple of 4 can be written as 4n where n = 1,2,3,...
then 4n = (n + 1)2 - (n - 1)2
However, unless you allow 1 = 12 - 02
1 cannot be so written as a difference of two squares
and odd multiples of 2 cannot be so written.
So that is the number 1 and 250 odd multiples of 2: 251 numbers in all.
1 cannot be so written.

∙ 13y agoRational numbers are numbers that can be written as a fraction. Irrational numbers cannot be expressed as a fraction. All natural and whole numbers are rational.
Natural numbers are basically counting numbers including zero (0,1,2,3,4,...) Since 6.40 can be written as a fraction, no, it is not a natural number.
Integers are those numbers that can be written without a fraction or decimal component, such as 1,200,37,-4 Natural numbers are the non negative integers.
The two binomials can be written as (x - a)(x + a), for any constant a. Proof: Expand using FOIL: (x - a)(x + a) = x2 + xa - xa - a2 Group: (x - a)(x + a) = x2 - a2 x2 - a2 is a difference of squares. Thus, the product of (x - a) and (x + a) is a difference of squares.
20 is both rational and natural. Rational numbers are numbers that can be written as a fraction. Irrational numbers cannot be expressed as a fraction.

Rational numbers are numbers that can be written as a fraction. Irrational numbers cannot be expressed as a fraction. All natural numbers are rational.
A rational number can be written as (one whole number) divided by (another whole number). An irrational number can't.
No. Odd numbers can be written as the sum of consecutive integers, but some multiples of odd numbers are even.
Yes.
