What is the difference between 2x and 2n?
This depends entirely on the context, but usually, an x denotes an unknown amount in an expression, while n denotes where a term is in a sequence. Examples: I have x amount of apples. My sister has twice that amount. How many does she have? 2x A sequence goes 1,2,3,4... etc. The term "n" is a certain amount. Which term is twice that amount? 2n This is how they are usually used, but they can also be interchangeable if you want to use them interchangeably. x and n both just mean "an unknown value".
