Need help with 7 and 8

Question 7 answer = 31

Question 8 answer = 128

Step-by-step explanation:

If n represents the number in the sequence, then for Question 7, you would do 5(8) - 9. 5 times 8 = 40 - 9 = 31.

Then, for question 8, 6-1 = 5, and you raise 2 to the 5th power because it is the one in parentheses. 2^5 = 32. Then, you multiply 4 times 32 to get 128.
