Arithmetic Sequence
Rational numbers are numbers that can be written as a fraction. Real numbers are any number, including irrationals.
2 , between every two odd numbers there is one even number
The sum or the difference between two irrational numbers could either be rational or irrational, however, it should be a real number.

Yes, the interval of a graph is the difference between any two consecutive numbers on a scale.For example, if the scale read: 2,4,6,8,10 then you could do 4-2, 6-4, etc. to find the interval. (which is 2)
This indicates that the scale used for the graph is 1 unit is 5 children. The distance between two numbers indicates a unit and this unit remains uniform throughout a scale. Thus, a scale plays a crucial part in plotting graphs. Without scales, we wonβt be able to infer anything relevant from the graph.
The difference is 2. (23 - 21 = 2).If we are talking about two odd numbers that come right after the number 20 then we mean the two consecutive odd numbers after 20.The difference between any consecutive odd numbers (or between any consecutive even numbers) is always 2.

The difference between ANY two numbers that are different, is positive. For example, the difference between -5 and -3 is 2. You can move two whole numbers either up from -5, or down from -3, on the number line.

This is a list of even numbers: 8, 2, 4, 6, ... This is a list of consecutive even numbers: 2, 4, 6, 8, .... The difference between any two consecutive even numbers is: 4-2=2 or 8-6=2 or 6-4=2 or ... The difference between any two consecutive even numbers is 2
The difference between any numbers is always positive.
Put all the numbers - zero, positive, negative - on a number line. Positive numbers to the left, negative numbers to the right. The difference between any two numbers is represented by the distance between them. Thus putting numbers on a number line is a great visualization tool.
