Question

I need help with this its from BIGIDEAS pls help

Answer 1

For explicit equations with the first term, you use the form
`f(n)=f_(1)+d(n-1)`. (f of 1 is the first term, d is the common difference, n is the step number)

However, since it is an admission fee before you go on rides, you do not need the -1 because it is not from the first term. Then, you can plug the values you know in.

f(n)=5+2n
