Question

A table of values of a linear function is shown in the image. Find the output when the input is n. Type your answer in the space provided.

Answer 1

You can rewrite as a sequence of values (the outputs): 2,5 ,8 , 11, ....

for the input 5, we must to have the output 14 (look that the sequence above, is take +3 every time)

So, for the input n, we must have

`3n - 1`

Why?

Look that, for n = 1, we need to have 2, and for n=2 we need to have 5, that correspond to take +3 for the predecessor...
