R was used for Real numbers. Q, for rational numbers refers to the fact that it must be possible to express them as quotients [of two integers].
Set of numbers made up of rational numbers and irrational numbers?
The real set, denoted R or ℝ.
What is the symbol of irrational numbers?
There is no special symbol.The set of rational numbers is denoted by Q and the set of real numbers by R so one option is R - Q.
What should be the next in the rational nos?
No idea what you're on about. If you are asking in what order do the sets of numbers apear in terms of proving there existence, I believe they are in the following order:N->Z->Q->R->CWhere: N is the set of natural numbers, i.e. whole numbers ranging from 1 to infinity.Z is the set or whole numbers including zero ranging from -infinity to +infinityQ is the set of rational numbers, i.e. the set of numbers that can be expressed in the form a/b where a and b are in Z with b not equal to 0.R is the set or real numbers, the collection of every rational and non rational number.C is the set of complex numbers, i.e. all numbers that can be expressed as a+biwhere a and b are in R and i is the squareroot of -1.
