Final answer:
To get a value 1 more than an initialized int variable x, the expression is x + 1. This basic algebraic expression increases the value of x by one, regardless of the context in which x is used.
Step-by-step explanation:
The question you're asking pertains to a basic algebraic operation. If an int variable x has already been declared and initialized, and you want an expression that gives a value that is 1 more than x, you simply need to add one to x. So the expression would be x + 1. In statistics, variables might represent categories such as the number of children in a family, and they can take on specific integer values (0, 1, 2, 3, etc.). This is different from intermediary algebra where variables are used more broadly in equations and algebraic expressions. In both cases, the concept of increasing a variable's value by one is the same, and is done by adding 1 to the variable.
