Answer:
an = (n+3)/(n+1)
Step-by-step explanation:
The sequence can be written as ...
4/2, 5/3, 6/4, 7/5, 8/6, ...
where the first numerator is n+3 and the first denominator is n+1. Each numerator and denominator increase by 1 from term to term, so the explicit formula can be written
an = (n+3)/(n+1)
Answer:John's error is that he applied the transformation rule to the image instead to the pre-image.The pre-image is the point you start with. To check the transformation rule, substitute the values of the coordinates (4, 5). This results to (4, 5) + (4+4, 5+7). Simplify to get (4, 5) → (8, 12). This is the image.
