How do you know which variable is the independent variable and which variable is the dependent variable in a real-world situation solving involving an arithmetic sequence?​

Answer 1

a variable (often denoted by y ) whose value depends on that of another.

This is for math of corse but we can use this to answer it, all you have to do is find the x which is time, then y is just the opposite of time, hope this helps. Let me know if you have any questions or want me to help you on a question I know my answer was a bit veg.
