Question

What are the first four terms of the sequence `r(n)=4.5n-8` ?

Answer 1

The first four terms are `-3.5, 1, 5.5, 10`

Explanation:

To solve this, simply plug 1, 2, 3, and 4 into the original function.

`r(1)=4.5(1)-8=-3.5`

`r(2)=4.5(2)-8=1`

`r(3)=4.5(3)-8=5.5`

`r(4)=4.5(4)-8=10`

So, the first four terms are `-3.5, 1, 5.5, 10`
