Sequence in a computer language means that programming statements are set out one after another. Unless the computer is told otherwise, it will carry out each instruction in turn.
Therefore a 'sequential language' such as Python or 'C' sets out source code instructions one after another.
In pseudocode, each instruction is set out like this
Do this Next do this Then do this ....
Once translated into a sequential programming language, it may look more like this:-
x = 3 MyVariable = 34 New_Variable = x + MyVariable
Usually the order of a sequence is important. For example the pseudocode below cannot work because New_Variable is trying to use MyVariable and x before they are given a value
New_Variable = x + MyVariable x = 3 MyVariable = 34
