Final answer:
The number in question is 4, as the equation n + 14 = 18 simplifies to n = 18 - 14 when solving for n.
Step-by-step explanation:
The question, 'Fourteen more than a number is eighteen,' can be translated into the equation n + 14 = 18. To find the value of n, we need to isolate n on one side of the equation. Doing so, we subtract 14 from both sides of the equation, which gives us n = 18 - 14. Therefore, the number we are looking for is 4.
