Does f(n)=2n-10 define the sequence -8, -6, -4

Question

trying to find the function that defines sequence -8, -6, -4

Answer 1

Try it yourself.  Be pro-active. Participate; try; learn, whether by success or failure (failure means...try again!).

 

f(1) = ?                   f(2) = ?

 

Is it working correctly?

Answer 2

I agree with Kenneth, and also suggest graphing or drawing a picture **always** and especially when you're stuck.
