I am guessing.
I think it is the answer you have in, I am not in that grade level yet so, I may be incorrect. Take care!
Sequence: 34, 42, 50, 58, 66
Since the difference between consecutive terms is 8, we deduce it is an arithmetic sequence, the recursive formula would be:

Given that the first term is 34 and the common difference is 8, the explicit formula would be:
Answer:
Step-by-step explanation:
It's unclear, but if is the question
12x-7=8
then
x=
