Answer:

a(n+1) = a(n) + 9

Step-by-step explanation:

The terms just before and just after each are 9 more than the previous term or 9 less than the previous term. In other words, the common difference is 9.

Thus, the recursive formula is a(n+1) = a(n) + 9

Annette [7]

Answer:

$\huge\boxed{\text{Translated left by 6 units, and down by 8}}$

Step-by-step explanation:

According to the rules f(x) --> f'(x + a) is a horizontal shift right by a factor of -a, and f(x) --> f'(x) + a is a horizontal shift up by a factor of a, you can deduce that because x becomes x + 6, and |x| becomes |x| - 8, the translations are as shown above.

Hope it helps :) and let me know if you want me to elaborate.
